Python Basics: Learn, Apply & Build Programs

 

Introduction

In today’s digital world, knowing how to program is becoming an essential skill—not just for computer scientists, but for anyone who works with data, automates tasks, or manages systems. Python is one of the best languages to start with: it’s readable, versatile, and well-supported. The course Python Basics: Learn, Apply & Build Programs is designed to introduce absolute beginners to Python programming — teaching not only syntax, but real application and problem-solving with code.

---

Why This Course Matters

Starting to program can be intimidating. Many new learners get stuck on setup, environment issues, or lose motivation because they don’t see how the pieces fit together. This course addresses those issues by:

• Guiding you through setting up Python and your development environment so you can write actual programs.

• Introducing key programming concepts (variables, loops, functions) in a structured way.

• Emphasising application and problem-solving: you don’t just learn syntax—you learn to build small programs and think like a programmer.

• Providing a solid stepping-stone: once you finish, you’ll be confident working in Python and ready to move into more advanced areas like data science, automation, or web development.

---

What the Course Covers

Here’s a breakdown of the key topics and learning outcomes:

Installation and Setup

The course begins by making sure you have Python installed, your editor or IDE working, and the ability to run scripts. This foundational step is often overlooked, yet it’s essential to ensure you can focus on programming—not debugging your setup.

Basic Syntax and Data Types

Learners are introduced to Python’s basic building blocks: variables, data types (strings, integers, floats), simple input/output, and basic operations. These are the tools you’ll use every day.

Control Flow: Conditionals and Loops

You’ll learn how your program can make decisions (if, else) and repeat tasks (for, while). These control structures let you build dynamic programs that respond to input or iterate over data.

Data Structures: Lists, Strings, Dictionaries

Programs become more powerful when they manage collections of data. The course introduces lists, strings, dictionaries (key-value pairs), how to manipulate them, how to access their elements, and how to use them in real logic.

Functions and Modular Code

Instead of writing giant scripts, you’ll learn to organise code into reusable pieces (functions), pass arguments, return values, and build program structure. This helps you keep your code clean and maintainable.

Problem-Solving and Program Building

The course emphasises applying what you learn: writing small programs that use loops, data structures and functions. Typical tasks might include generating sequences (like Fibonacci), validating input, creating simple calculators or pattern-printing. This transforms the knowledge into skill.

---

Who Should Take This Course

This course is ideal for:

• Absolute beginners: People who have little to no programming experience and want a gentle, structured introduction.

• Non-CS professionals: If you work in a field like business, engineering, marketing or data and want to pick up programming to automate tasks or analyse data.

• Students preparing for CS or data roles: If you plan to go deeper later (data science, web dev), this course gives you the foundation you’ll need.

If you are already comfortable writing code, working with data structures and building programs, you may find some material in this course basic—but it could still serve as a good refresher or clean up your fundamentals.

---

What You’ll Walk Away With

By the end of the course you will:

• Be comfortable installing and running Python and writing basic scripts.

• Understand and use core programming constructs: variables, data types, loops, conditionals.

• Manipulate data using lists, strings and dictionaries.

• Write functions to modularise your programs.

• Have solved small programming challenges that build your logical thinking and coding confidence.

• Be ready for more advanced programming topics: file I/O, web scraping, data analysis, automation, or building full applications.

---

Tips to Get the Most Out of This Course

• Code along: Don’t just watch the videos. Pause, open your code editor, type the examples, experiment. This helps you remember.

• Try variations: After writing a program as shown, change parts of it—add features, tweak input, handle edge cases. This deepens your learning.

• Work on small tasks: After you finish a module, try to build one small script of your own (e.g., a simple text-menu utility or number-game) using what you learned.

• Keep practising: Even after the course, build tiny scripts to automate daily tasks or process data. These reinforce your skills and build your confidence.

• Document your code: Write comments, use readable variable names, keep your code clean. Habitual good practice early helps later on.

Python Coding challenge - Day 807| What is the output of the following Python Code?

 

Code Explanatiion:

1. import json

This line imports Python’s json module, which is used for working with JSON data.

It allows converting Python objects to JSON strings and vice-versa.

2. data = {"name": "John", "age": 25}

A Python dictionary named data is created.

It contains two key-value pairs:

{

    "name": "John",

    "age": 25

}

3. js = json.dumps(data)

json.dumps() converts a Python dictionary into a JSON-formatted string.

After conversion, js becomes:

'{"name": "John", "age": 25}'

Notice that the result is a string, not a dictionary.

4. length = len(js)

len(js) calculates the total number of characters in the JSON string.

It counts every character, including braces {}, quotes " ", spaces, colons :, and commas ,.

5. print(js[2], length)

js[2] prints the 3rd character of the JSON string (indexing starts from 0).

length prints the total character count.

Given the string:

{"name": "John", "age": 25}

 0 1 2 ...

At index 2, the character will be:

n

So the output will look something like:

n 27

Final Output:

n 27

Python Coding challenge - Day 806| What is the output of the following Python Code?

 

Code Explanation:

1. import itertools

This line imports the itertools module from Python’s standard library.

itertools provides fast, memory-efficient tools for working with iterators.

2. nums = range(10)

range(10) creates a sequence of numbers from 0 to 9 (10 is not included).

So, nums represents:

0, 1, 2, 3, 4, 5, 6, 7, 8, 9

3. slice_obj = itertools.islice(nums, 2, 6)

itertools.islice() works like slicing but on iterators.

Parameters: (iterable, start, stop)

start = 2

stop = 6

This takes elements from index 2 up to (but not including) 6.

Index positions → 0:0, 1:1, 2:2, 3:3, 4:4, 5:5, 6:6 ...

So it slices out:

2, 3, 4, 5

4. result = list(slice_obj)

Converts the sliced iterator into a list.

Now result becomes:

[2, 3, 4, 5]

5. print(result[0], result[-1])

result[0] → first element = 2

result[-1] → last element = 5

So the output will be:

2 5

Final Output

2 5

Python Coding Challange - Question with Answer (01241025)

 

Step 1: Loop Execution

for i in range(3): 
    x = i

• The loop runs 3 times — for i = 0, 1, and 2.

• Each time, x is assigned the value of i.

• After the loop finishes, x remains as the last value assigned → x = 2.

So now:

x = 2

🔹 Step 2: Function Definition

def test(): 
    print(x)

This defines a function named test, but it doesn’t execute yet.

🔹 Step 3: Function Call

test()

When test() runs:

• Python looks for the variable x inside the function (local scope).

• It doesn’t find one, so it looks outside the function (global scope).

• There it finds x = 2.

✅ Output:

2
 Key Concept — Scope:

• Local scope: Variables declared inside a function.

• Global scope: Variables declared outside functions.

• If a function doesn’t have a local variable with the same name, it uses the global variable.

Python Coding challenge - Day 797| What is the output of the following Python Code?

 

Code Explanation:

Importing the Altair Library

import altair as alt

What it does:

Imports the Altair library and gives it the short alias alt.

Why:

Altair is a declarative data visualization library for Python — you describe what you want to visualize (not how to draw it). It integrates very well with Pandas dataframes and Vega-Lite under the hood.

Importing the Pandas Library

import pandas as pd

What it does:

Imports the Pandas library with the alias pd.

Why:

Pandas provides powerful data structures like DataFrame — ideal for storing and manipulating tabular data (rows and columns).

Creating a Pandas DataFrame

df = pd.DataFrame({'x':[1,2,3], 'y':[4,5,6]})

What it does:

Creates a small DataFrame with two columns:

'x' = [1, 2, 3]

'y' = [4, 5, 6]

So the DataFrame looks like this:

   x  y

0  1  4

1  2  5

2  3  6

Why:

This serves as the data source for the chart.

Each row will represent one bar in the bar chart.

Creating an Altair Chart Object

chart = alt.Chart(df).mark_bar().encode(x='x', y='y')

What it does:

alt.Chart(df) creates a Chart object using the DataFrame df as the data source.

.mark_bar() specifies that you want a bar chart (as opposed to points, lines, etc.).

.encode(x='x', y='y') tells Altair how to map data columns to visual elements:

The column 'x' goes on the x-axis.

The column 'y' goes on the y-axis.

Why:

This single line fully defines the bar chart’s structure — Altair takes care of rendering the visualization using Vega-Lite automatically.

Printing the Column Names

print(list(df.columns))

What it does:

df.columns gives an Index object containing the column names (Index(['x', 'y'], dtype='object')).

Wrapping it in list() converts it to a normal Python list.

print() outputs that list to the console.

Output:

['x', 'y']

Python Coding Challange - Question with Answer (01231025)

 

Step-by-step execution:

Initial array:
arr = [1, 2, 3]

The for loop iterates over the list, but note — the list is changing during iteration.

---

Iteration 1:

i = 1

• arr.remove(1) → removes the first occurrence of 1

• Now arr = [2, 3]

But — Python’s for loop moves to the next index (index 1)
👉 So now it skips checking the element at index 0 (which became 2 after removal).

---

Iteration 2:

• Next element (at index 1) is 3

• arr.remove(3) removes 3

• Now arr = [2]

---

Loop ends (because Python has already iterated through what it thinks were 3 elements).

---

✅ Final Output:

[2]

---

🔹 Why does this happen?

Because modifying a list while looping over it confuses the iterator —
the loop skips elements since the list shrinks and indexes shift.

---

💡 Best Practice:

Never modify a list while iterating over it.
Instead, use a copy:

arr = [1, 2, 3]
for i in arr[:]:
    arr.remove(i)
print(arr) # Output: []

---

So the correct answer is ✅ [2]

Python Coding challenge - Day 803| What is the output of the following Python Code?

 

Code Explanation:

Import the Library

import statistics as st

Imports Python’s built-in statistics library.

The alias st is used to make function calls shorter (ex: st.mean() instead of statistics.mean()).

Create a List of Data

data = [2, 4, 6, 8, 10]

A list named data is created containing five numeric values.

We will use this list to calculate statistical values.

Calculate the Mean (Average)

mean_val = st.mean(data)

st.mean(data) calculates the mean (average) of the list.

Mean formula = (2 + 4 + 6 + 8 + 10) / 5 = 30 / 5 = 6

The result is stored in the variable mean_val.

Calculate the Median (Middle Value)

median_val = st.median(data)

st.median(data) finds the median (middle number).

The sorted list is [2, 4, 6, 8, 10] — the middle value is 6

The result is stored in the variable median_val.

Print the Results

print(mean_val, median_val)

Prints both values in one line.

Output will be:

6 6

Python Coding challenge - Day 802| What is the output of the following Python Code?

Code Explanation:

Import the Required Function

from functools import lru_cache

This imports lru_cache from Python’s functools module.

lru_cache is used to store (cache) function results, so repeated calls with the same input run faster.

Apply the lru_cache Decorator

@lru_cache(None)

This decorator is applied to the function below it.

None means unlimited cache size (no limit).

After applying this, Python will remember the output of the function for each unique input.

Define the Function

def f(x): return x*2

Defines a function f that returns x * 2.

Example: if x = 5, the function output is 10.

Call the Function First Time

f(5)

This calls the function with value 5.

Since it's the first time, the value is computed and stored in cache.

Result = 10 (but nothing is printed yet, because there is no print())

Call the Function Second Time (Cached Result)

f(5)

Same input again → lru_cache returns the stored result from memory.

The function does not compute again (faster), but again nothing is printed.

Print Final Output

print("Done")

Final Output:

Done

What really sets someone apart is the ability to apply skills in meaningful projects—whether it’s web apps, automation tools, data solutions or AI-driven agents. The course The Python Mega Course: Build 20 Real-World Apps and AI Agents is designed exactly for that: it goes beyond theory and guides you through building 20 distinct applications using Python, including AI agents, from scratch. If you are looking to move from “I know Python” to “I build useful things with Python”, this course could be a strong fit.

---

Why This Course Matters

There are countless Python courses that teach you syntax, control flow, data structures and maybe small examples. But many learners get stuck at “hello world” or “basic script” level. This course shifts the emphasis to application and breadth: you don’t just learn Python, you use Python to create real applications that mirror what you might encounter in a job or startup environment. By the end, you’re not just more knowledgeable—you’re more capable. This kind of hands-on, project-centric learning helps close the gap between learning and doing.

---

What You Will Learn – Course Highlights

Here’s a breakdown of what the course covers and what you’ll walk away with:

1. Comprehensive Application Building

You’ll build 20 real-world applications, each one focusing on a different domain or level of complexity. That could include automation scripts, web applications, data processing tools, GUI desktop apps, web scraping, and AI agents. The variety helps you see how Python applies across different problem sets and gives you a broad portfolio of work.

2. From Beginner to Pro in Python

The course is structured to take you from the basics—installing Python, writing your first scripts, understanding data types and control flow—through to advanced applications. As you progress, you’ll pick up modules, frameworks, libraries and best practices that let you build more professional systems.

3. Integrating Modern Tools and Libraries

Modern Python development isn’t just “write a script”. The course introduces you to libraries and frameworks used in real development: for example web frameworks (Flask, Django), GUI libraries (PyQt, etc.), automation tools (Selenium, etc.), data manipulation with Pandas, and even AI/agent frameworks (e.g., LangChain or other agent-oriented libraries). These give you exposure to the tools used in production settings.

4. Building AI Agents and Intelligent Applications

A standout component is the AI-agent building segment. You’ll learn how to design systems that leverage Python + modern AI/agent frameworks: agents that act, reason, interact, perhaps orchestrate tasks, integrate APIs and make decisions. This covers one of the most sought-after skill sets in 2025: building intelligent applications, not just static ones.

5. Hands-On, Project-First Learning

Rather than long lectures of theory, the course emphasizes doing. You build, you run, you debug, you iterate. By completing apps, you not only learn concepts—you internalize them. This accelerates your readiness to tackle your own side projects or job assignments.

---

Who Should Take This Course

• Absolute beginners: If you’ve never programmed before but are motivated to build apps and make things happen, this course will take you from zero to building real applications.

• Python developers with some experience: If you know the basics of Python but haven’t built many full-scale applications, this course will deepen your ability to create production-style apps and use libraries/frameworks.

• Aspiring automation or AI engineers: If you want to learn how Python is used in automation, AI agents or glue-code to tie systems together, you’ll find relevant content here.

• Side-project builders and hobbyists: If you like building things (automation tools, web apps, scrapings, agents) for your own use or for fun, the course gives you templates and guidance to make that happen.

If you’re already an advanced software engineer working on large distributed systems or specialized ML research, parts of this might feel basic—but you could still benefit from the breadth and application angle.

---

What You’ll Walk Away With

After finishing the course you will likely be able to:

• Use Python confidently for building applications, not just scripts.

• Understand and use a variety of libraries and frameworks (web, GUI, automation, data, agents).

• Build several complete applications to showcase in your portfolio (20 is a large number).

• Design, implement and deploy an AI agent or intelligent application using Python.

• Be prepared to take on freelance projects, personal side-apps, or further move into data science, web development or AI systems.

---

Tips to Get the Most Out of It

• Follow the projects fully: Build each app, run it, modify it. Don’t skip exercises—the value comes from building.

• Extend the projects: After completing the guideline version, add new features or change behaviour. That helps go beyond what’s taught and makes the learning “yours”.

• Use your own ideas: Once you’ve built several apps, think of your own app idea and apply what you learnt to it. That consolidates learning and gives you something unique to show.

• Reflect on architecture: When building apps and agents, think about how you’d maintain, scale or deploy them—this mindset helps your work align with real-world expectations.

• Document your work: Push your code to GitHub, write a short README for each project, maybe include screenshots or videos of them running. A portfolio of 20 projects plus descriptions stands out.

Python for Machine Learning & Data Science Masterclass

Introduction

In the era of big data and AI, the ability to analyze data, build predictive models and derive insights has become a key skill. Python is the language of choice for many data scientists and machine learning engineers because of its simplicity and powerful ecosystem. The Python for Machine Learning & Data Science Masterclass is designed to take you from relevant Python programming into full-fledged data science and machine learning workflows, not only teaching you libraries, but how to build end-to-end workflows.

---

Why This Course Matters

Here are a few reasons why this course stands out:

• It not only teaches Python, but uses Python for data science and machine learning: covering libraries like NumPy (numerical computing), Pandas (data manipulation), Matplotlib/Seaborn (visualization), Scikit-Learn (machine learning) and more.

• It emphasises real-world workflows: you build data pipelines, analyze datasets, create visualizations, engineer features, train models and deploy insights.

• It helps you build a portfolio of projects with real datasets, making your skills visible to potential employers or collaborators.

• It bridges the gap between just writing Python code and applying it in data science / machine learning tasks: understanding why you pick an algorithm, how you evaluate it, how you extract features, how you visualize results.

---

Course Structure & Key Topics

Here’s an overview of what the course typically covers:

Setup & Python Refresher

The course begins by ensuring your environment is set up (Anaconda, Jupyter notebooks or IDEs) and refreshing Python fundamentals. If you already know Python basics, you’ll move quickly through this section into data science-specific topics.

Numerical & Data Libraries

You’ll dive into NumPy to handle arrays and efficient numeric computation. Then you’ll use Pandas for manipulating tabular data: selecting, filtering, aggregating, cleaning. This is the core of real-world data science because real datasets are messy, large, and require preprocessing.

Data Visualization

Using libraries like Matplotlib and Seaborn, you’ll learn how to visualize distributions, relationships, time-series, categorical vs continuous variables. Good visualizations not only help you understand your data, but also communicate insights to stakeholders.

Machine Learning Fundamentals

You’ll move into supervised learning: regression (predict continuous outcomes), classification (predict categories) using algorithms like linear regression, logistic regression, support vector machines, decision trees, random forests. You’ll also work on unsupervised learning: clustering (K-Means, Hierarchical, DBSCAN), dimensionality reduction (PCA). You’ll apply these algorithms, understand their assumptions and the steps to build a workflow: feature engineering → model training → evaluation.

Feature Engineering & Model Evaluation

A major part of model performance comes from how well you engineer features and evaluate models. The course covers creating new features, handling missing data, encoding categories, scaling features, cross-validation, grid search, hyperparameter tuning, overfitting vs underfitting, bias-variance tradeoff.

Real-World Projects & Portfolio Building

The course includes project work based on real datasets. The idea is you complete end-to-end tasks: data ingestion, cleaning, exploration, modeling, evaluation, interpretation. These become portfolio items you can display to employers or use in your own work.

Deployment & Workflow

Finally, you learn about the full workflow: how a data science or machine learning project might go from prototype to production. This includes saving models, making predictions on unseen data, perhaps deploying via API or building a dashboard. Understanding the lifecycle is what separates “I trained a model” from “I built a usable solution”.

---

Who Should Take This Course

This course is ideal if you:

• Have basic familiarity with Python (or programming in general) and want to apply it in data science or machine learning.

• Want to move into a data science/ML role or build data-driven solutions in your current role.

• Prefer hands-on learning: you want to do projects, not just watch lectures.

• Want to build a solid portfolio of work that demonstrates your skills rather than just a certificate.

If you are already very advanced in ML (deep neural networks, production MLops at scale), this course may cover topics you already know, but it could still be useful as a refresher or to fill gaps.

---

What You’ll Walk Away With

By the end of the course you will likely be able to:

• Write Python code effectively for data science tasks (data cleaning, manipulation, visualization).

• Use major Python libraries – NumPy, Pandas, Matplotlib/Seaborn, Scikit-Learn – in applied workflows.

• Build and evaluate machine learning models for classification and regression.

• Undertake feature engineering, data preprocessing and model tuning.

• Understand the workflow of a data science/ML project from raw data to insights to deployment.

• Have completed portfolio-ready projects you can show to others.

• Be better prepared to pursue roles in data science, analytics, ML engineering or to apply these skills in your domain.

---

Tips to Get the Most Out of It

• Follow the project assignments closely**– make sure you write the code, run it, debug it. Passive watching won’t help as much as active doing.

• Modify each project – after finishing the code as shown, tweak it. Change features, try different algorithms, visualize new things. This deepens your understanding.

• Use your own datasets – if possible, apply the workflows to a dataset of your interest (from Kaggle or your domain). This helps you internalize the workflow and also builds domain relevance.

• Keep practising after the course ends – data science and ML are skills that grow with regular use. Try mini-projects, Kaggle competitions, automation tasks.

• Document your work – use GitHub to push your notebooks, include README files, summarise findings. A well-documented portfolio is more impressive than just raw code.

---

Why This Course Matters

Learning programming can often feel abstract: syntax rules, data types, functions. But until you apply what you’ve learned in a project, the knowledge remains inert. This course flips that script: you learn by building. By doing 24 projects, you amass experience in writing code, solving problems, debugging, structuring your program, integrating modules, and seeing results. That’s the kind of experience many employers and practical programmers value.

Because the projects build on each other (or at least cover different aspects of Python), you also gain breadth: scripts, tools, applications, maybe small games or utilities. This broad exposure helps you decide which direction you want to head (web dev, data science, automation) and gives you confident familiarity with Python.

What You Will Learn / Course Structure

Here’s an overview of what the course typically covers:

1. Setup & Fundamentals

You begin by installing Python, setting up your IDE or editor, understanding how to run Python scripts, and getting comfortable with basic syntax: variables, data types, input/output, and basic control flow.

2. Control Flow & Data Structures

Next you dive into loops, conditionals, lists, dictionaries, sets, tuples—Python’s core data structures. You’ll build small scripts that manipulate data, process input, and produce output. These foundations are critical for any project.

3. Functions, Modules & Error Handling

Once you’re comfortable with data structures, the course moves into defining your own functions, using modules, organizing your code into reusable parts, and handling errors/exception. Good programming style begins here.

4. Object-Oriented Programming (OOP)

At this stage you’ll learn how to define classes and objects in Python—how to encapsulate data and behaviors, how to use inheritance or composition, and how to build more structured programs. This is important for larger projects.

5. Project-based Learning

The heart of the course is the 24 projects. Each project gives you a concrete goal: for example a text-processing tool, a mini game, a web scraper, a GUI utility, or an automation script. These projects integrate what you’ve learned and challenge you to apply it. You write, test, debug, and iterate.

6. Preparing for Real-World Use

By the end, you’ll not only know how to write Python code—but you’ll have a portfolio of projects you can show, and you will be ready to move into more specialized domains like web development (Flask/Django), data science (Pandas/Numpy), automation (scripts/tools), or even machine learning (basic pipelines).

---

Who Should Take This Course

This course is ideal if you are:

• A complete beginner in programming who wants to learn Python from scratch.

• Someone who already knows some programming but wants to strengthen Python skills by building actual projects.

• A learner who prefers learning by doing—building projects rather than just watching theory.

• Interested in automating tasks, building utilities, starting a Python-based portfolio, or exploring Python’s many use-cases.

If you’re already an experienced developer working on advanced projects, this course may seem basic—but it still offers value in filling gaps, building a portfolio, and reinforcing good habits.

• Possess confidence in your ability to start, build, test and finish a Python project.

---

Tips to Get the Most Out of It

• Do each project: don’t skip the coding. Build, run, break it, fix it. That’s how you learn.

• Modify the projects: Once you finish a project, try adding a feature or changing logic. It deepens understanding.

• Keep practicing daily: Even short daily practice helps more than long but sporadic sessions.

• Use your own ideas: After finishing the course, pick your own project and apply what you’ve learned to it—this is where you solidify skills.

• Document your work: Write comments, create README files for your projects, and add them to a GitHub repo. This builds your portfolio.

Python Coding challenge - Day 805| What is the output of the following Python Code?

 

Code Explanation:

Import deque from collections

from collections import deque

deque is a special data structure from the collections module.

It stands for Double Ended Queue, meaning you can add or remove items from both left and right ends efficiently.

Create a deque

dq = deque([10, 20, 30])

A deque named dq is created with initial elements 10, 20, 30.

The structure now looks like: [10, 20, 30]

Append an Element to the Right Side

dq.append(40)

append(40) adds 40 to the right end of the deque.

Now the deque becomes: [10, 20, 30, 40]

Append an Element to the Left Side

dq.appendleft(5)

appendleft(5) adds 5 to the left end.

Now the deque becomes: [5, 10, 20, 30, 40]

Print First and Last Elements

print(dq[0], dq[-1])

dq[0] → first element = 5

dq[-1] → last element = 40

Output:

5 40

Final Output

5 40

Python Coding challenge - Day 804| What is the output of the following Python Code?

 

Code Explanation:

Import the Math Module

import math

Imports Python’s math module.

This module provides mathematical functions like sqrt() and pow().

Create a List of Numbers

nums = [9, 25, 49]

A list named nums is created.

It contains three perfect square numbers: 9, 25, and 49.

Calculate Square Roots Using List Comprehension

roots = [math.sqrt(i) for i in nums]

math.sqrt(i) computes the square root of each number in the list.

List comprehension runs sqrt() on 9, 25, and 49 and stores the results in roots.

So roots becomes: [3.0, 5.0, 7.0]

Square the First Root

sq = math.pow(roots[0], 2)

roots[0] is 3.0

This reverses the square root operation for the first element.

Print Required Values

print(roots[1], sq)

roots[1] is the second square root → 5.0

sq is 9.0

Final output:

5.0 9.0

Final Output

5.0 9.0
