Python Coding Challenge - Question with Answer (ID -080426)

 

Explanation:

🔹 1. List Initialization

lst = [1, 2, 3]

A list named lst is created.

It contains three elements: 1, 2, 3.

👉 After this line:

lst = [1, 2, 3]

🔹 2. Using extend() Method

lst.extend([4, 5])

The extend() method adds elements of another list to the existing list.

It modifies the original list in-place (does NOT create a new list).

👉 After this operation:

lst = [1, 2, 3, 4, 5]

🔹 3. Return Value of extend()

Important point:

extend() returns None

It does NOT return the updated list

🔹 4. Print Statement

print(lst.extend([4, 5]))

First, lst.extend([4, 5]) executes:

List becomes: [1, 2, 3, 4, 5]

Then print() prints the return value of extend()

Which is: None

👉 Output:

None

🔹 5. Final State of List

Even though output is None, the list is updated:

print(lst)

👉 Output:

[1, 2, 3, 4, 5]

Day 5: Conditional Statements in Python

Making Decisions in Your Code 

---

 Introduction

In real life, we make decisions all the time:

• If it rains → take an umbrella
• If marks ≥ 90 → Grade A
• If balance is low → show warning

Similarly, in programming, we use conditional statements to control the flow of execution.

---

 What are Conditional Statements?

Conditional statements allow a program to make decisions based on conditions.

They help programs:

• Execute different blocks of code
• Respond dynamically to input
• Implement logic like real-world systems

---

 Core Idea

# if condition is True -> run code
# else -> skip or run something else

---

 1. if Statement

 Syntax

if condition:
    # code block

 Example

age = 18

if age >= 18:
    print("You can vote")

 Runs only when condition is True

---

 2. if-else Statement

Syntax

if condition:
    # True block
else:
    # False block

 Example

num = 5

if num % 2 == 0:
    print("Even")
else:
    print("Odd")

---

 3. if-elif-else Statement

 Used when multiple conditions exist

 Syntax

if condition1:
    # block1
elif condition2:
    # block2
else:
    # default block

 Example

marks = 94

if marks >= 90:
    print("Grade A")
elif marks >= 75:
    print("Grade B")
elif marks >= 50:
    print("Grade C")
else:
    print("Fail")

---

 Important Rule

 Only ONE block executes
 First True condition wins

---

 4. Nested Conditions

 Condition inside another condition

 Example

age = 20
has_id = True

if age >= 18:
    if has_id:
        print("Entry Allowed")
    else:
        print("ID required")
else:
    print("Underage")

---

 Important Concepts (Must Understand)

 Truthy & Falsy Values

if 0:
    print("Hello")
else:
    print("World")

 Output: World

---

 Truth Table

• 0, None, False, "" → Falsy
• Everything else → Truthy

---

 Order Matters

marks = 90

if marks >= 50:
    print("Pass")
elif marks >= 90:
    print("Topper")

 Output: Pass (because first condition matched)

---

---

 Practice Problems

 Basic Level

1. Check whether a number is positive or negative.

1. Check whether a number is even or odd.

1. Find the greater number between two numbers.

---

 Intermediate Level

4. Find the greatest among three numbers.

4. Check whether a given year is a leap year.

4. Create a grade system based on marks:

• 90 and above → Grade A

• 75 to 89 → Grade B

• 50 to 74 → Grade C

• Below 50 → Fail

---

 Advanced Level

7. Check whether a given number is a palindrome.

7. Build logic for an ATM withdrawal system:

• Check if balance is sufficient

• Check if amount is a multiple of 100

7. Create a login system:

• Validate username and password

• Show success or error message

🚀 Day 14/150 – Convert Celsius to Fahrenheit in Python 🌡️

 

🚀 Day 14/150 – Convert Celsius to Fahrenheit in Python

Temperature conversion is one of the most common beginner-friendly problems in programming. It helps you understand formulas, user input, functions, and even advanced concepts like list comprehensions.

The formula used is:

$$F = (C \times \frac{9}{5}) + 32$$

Let’s explore multiple ways to implement this in Python 👇

🔹 Method 1 – Direct Conversion

This is the simplest and most straightforward approach.

celsius = 25 fahrenheit = (celsius * 9/5) + 32 print("Temperature in Fahrenheit:", fahrenheit)

✅ Explanation:

• We directly assign a value to celsius
• Apply the formula
• Print the result

👉 Best for: Quick calculations or testing

🔹 Method 2 – Using User Input

This makes your program interactive.

celsius = float(input("Enter temperature in Celsius: ")) fahrenheit = (celsius * 9/5) + 32 print("Temperature in Fahrenheit:", fahrenheit)

✅ Explanation:

• input() takes user input as string
• float() converts it into a number
• Formula is applied as usual

👉 Best for: Real-world programs where users provide input

🔹 Method 3 – Using a Function

Functions make your code reusable and cleaner.

def celsius_to_fahrenheit(c):
    return (c * 9/5) + 32

print(celsius_to_fahrenheit(25))

✅ Explanation:

• Function takes input c
• Returns converted value
• Can be reused multiple times

👉 Best for: Clean and modular code

🔹 Method 4 – Using Lambda Function (One-liner)

A shorter version of functions.

convert = lambda c: (c * 9/5) + 32 print(convert(25))

✅ Explanation:

• lambda creates an anonymous function
• Useful for quick operations

👉 Best for: Short, one-time use functions

🔹 Method 5 – Using List Conversion

Convert multiple values at once.

celsius_values = [0, 10, 20, 30]

fahrenheit_values = [(c * 9/5) + 32 for c in celsius_values]

print(fahrenheit_values)

✅ Explanation:

• Uses list comprehension
• Converts each value in the list
• Efficient and Pythonic

👉 Best for: Bulk data processing

⚡ Key Takeaways

• Always remember the formula: (C × 9/5) + 32
• Use float() when taking decimal inputs
• Functions improve reusability
• Lambda is great for quick operations
• List comprehensions are powerful for handling multiple values
