Python Coding Challange - Question with Answer (01280525)

 

What does it do?

Outer Loop:

for i in range(1, 3):

• range(1, 3) generates numbers: 1, 2

• So, the loop runs 2 times, with i = 1 then i = 2

---

Inner Loop:

for j in range(2):

• range(2) generates numbers: 0, 1

• So, for each i, this inner loop runs twice, with j = 0, then j = 1

---

Inside Both Loops:

print(i + j)

• It prints the sum of i and j for each combination

---

 Iteration Breakdown:

i	j	i + j	Output
1	0	1	✅
1	1	2	✅
2	0	2	✅
2	1	3	✅

 Final Output:

1  
2 
2
3

---

 Summary:

• This is a nested loop.

• The outer loop controls i = 1, 2

• The inner loop controls j = 0, 1

• The program prints the sum of i + j for each combination.

fig = plt.figure()

ax = fig.add_subplot(111, projection='3d')

num_steps = 50         

height_per_step = 0.2  

radius = 2             

theta = np.linspace(0, 4 * np.pi, num_steps)  

x = radius * np.cos(theta)

y = radius * np.sin(theta)

z = height_per_step * np.arange(num_steps)

ax.scatter(x, y, z, c='brown', s=100, label='Steps')

ax.plot([0,0], [0,0], [0, z[-1]+1], color='grey', linestyle='--', linewidth=2, label='Central Pole')

ax.set_xlabel('X')

ax.set_ylabel('Y')

ax.set_zlabel('Z (height)')

ax.legend()

plt.show()

#source code --> clcoding.com 

Code Explanation:

1. Import Libraries

import numpy as np

import matplotlib.pyplot as plt

numpy for numerical operations and array handling.

matplotlib.pyplot for plotting graphs.

 2. Create Figure and 3D Axes

fig = plt.figure()

ax = fig.add_subplot(111, projection='3d')

Creates a new plotting figure.

Adds a 3D subplot to the figure (one plot, with 3D projection).

 3. Define Parameters for Staircase

num_steps = 50         # Number of steps in the staircase

height_per_step = 0.2  # Height increase for each step

radius = 2             # Radius of spiral path

Sets how many steps.

How much each step rises vertically.

How far each step is from the center.

 4. Calculate Step Angles

theta = np.linspace(0, 4 * np.pi, num_steps)

Creates num_steps angles evenly spaced from 0 to

4π (two full rotations).

 5. Calculate Step Positions (x, y, z)

x = radius * np.cos(theta)

y = radius * np.sin(theta)

z = height_per_step * np.arange(num_steps)

Computes x, y coordinates on a circle of given radius (using cosine and sine).

 z increases linearly with step number, creating height.

 6. Plot Steps as Points

ax.scatter(x, y, z, c='brown', s=100, label='Steps')

Plots each step as a brown dot sized 100.

Labels them for the legend.

 7. Plot Central Pole

ax.plot([0,0], [0,0], [0, z[-1]+1], color='grey', linestyle='--', linewidth=2, label='Central Pole')

Draws a vertical dashed line at the center representing the staircase pole.

Goes from height 0 to just above the last step.

 8. Set Axis Labels

ax.set_xlabel('X')

ax.set_ylabel('Y')

ax.set_zlabel('Z (height)')

Labels each axis to indicate directions.

 9. Add Legend

ax.legend()

Adds a legend explaining plotted elements (steps and pole).

 10. Display the Plot

plt.show()

Shows the final 3D spiral staircase plot.

3D Conch Shell Structure using Python

 

import numpy as np

import matplotlib.pyplot as plt

from mpl_toolkits.mplot3d import Axes3D

theta = np.linspace(0, 8 * np.pi, 500)   

z = np.linspace(0, 2, 500)               

r = z**2 + 0.1                           

phi = np.linspace(0, 2 * np.pi, 50)

theta, phi = np.meshgrid(theta, phi)

z = np.linspace(0, 2, 500)

z = np.tile(z, (50, 1))

r = z**2 + 0.1

x = r * np.cos(theta) * np.cos(phi)

y = r * np.sin(theta) * np.cos(phi)

z = r * np.sin(phi)

fig = plt.figure(figsize=(6, 6))

ax = fig.add_subplot(111, projection='3d')

ax.plot_surface(x, y, z, cmap='copper', edgecolor='none', alpha=0.9)

ax.set_title('3D Conch Shell ', fontsize=14)

ax.set_box_aspect([1,1,1])

ax.axis('off') 

plt.show()

#source code --> clcoding.com

Code Explanation:

1. Import Libraries

import numpy as np

import matplotlib.pyplot as plt

from mpl_toolkits.mplot3d import Axes3D

numpy is for numerical arrays and functions.

matplotlib is for plotting.

Axes3D is needed to enable 3D plotting in matplotlib. 

2. Define Spiral Parameters

theta_vals = np.linspace(0, 8 * np.pi, 500)  # Spiral angle: 0 to 8π

z_vals = np.linspace(0, 2, 500)              # Vertical height

phi_vals = np.linspace(0, 2 * np.pi, 50)     # Circular angle around shell's axis

theta_vals: Controls how many times the spiral wraps around — 4 full rotations.

z_vals: The height (like vertical position in the shell).

phi_vals: Describes the circle at each spiral point (the shell's cross-section). 

3. Create 2D Grids

theta, phi = np.meshgrid(theta_vals, phi_vals)

meshgrid creates a 2D grid so we can compute (x, y, z) coordinates across both theta and phi.

theta and phi will be shape (50, 500) so that we can build a surface. 

4. Define Radius and Z

z = np.linspace(0, 2, 500)

z = np.tile(z, (50, 1))       # Repeat z rows to shape (50, 500)

r = z**2 + 0.1                # Radius grows quadratically with height

z is tiled to match the (50, 500) shape of theta and phi.

r = z^2 + 0.1: Makes the radius increase faster as you go up, giving the shell its expanding spiral. 

5. Compute 3D Coordinates

x = r * np.cos(theta) * np.cos(phi)

y = r * np.sin(theta) * np.cos(phi)

z = r * np.sin(phi)

This is the parametric equation for a growing spiral swept by a circle.

theta sweeps the spiral.

phi creates a circular cross-section at each spiral point. 

The cos(phi) and sin(phi) give the circular shape.

r * cos(theta) and r * sin(theta) give the spiral path. 

6. Plotting the Shell

 fig = plt.figure(figsize=(10, 8))

ax = fig.add_subplot(111, projection='3d')

 ax.plot_surface(x, y, z, cmap='copper', edgecolor='none', alpha=0.9)

ax.set_title('3D Conch Shell Structure', fontsize=14)

ax.set_box_aspect([1,1,1])

ax.axis('off')

plt.show()

plot_surface(...): Renders a 3D surface using x, y, z.

 cmap='copper': Gives it a warm, shell-like color.

 ax.axis('off'): Hides the axis to enhance the visual aesthetics.

 set_box_aspect([1,1,1]): Keeps the plot from being stretched.

Python Coding challenge - Day 511| What is the output of the following Python Code?

 

Code Explanation:

 Line 1: Function Definition

def func(x, y=5, z=None):

func is a function with 3 parameters:

x: required argument.

y: optional, default value is 5 (not used here).

z: optional, default is None.

Line 2–3: Check and Create List if Needed

    if z is None:

        z = []

If z is None, a new empty list is created.

This ensures that a new list is created for every call, avoiding shared mutable state.

Line 4: Append to List

    z.append(x)

Adds the value of x to the list z.

Line 5: Return the List

    return z

Returns the updated list.

Function Calls and Outputs

Call 1: func(1)

z is None → creates new list [].

Appends 1 → becomes [1].

Returns [1].

Output:

[1]

Call 2: func(2)

Again, z is None → new list [].

Appends 2 → becomes [2].

Returns [2].

Output:

[2]

Final Output:

[1]

[2]

Python Coding challenge - Day 510| What is the output of the following Python Code?

 

Code Explanation:

Line 1: Function Definition

def tricky(val, s=set()):

Defines a function tricky with two parameters:

val: the value to add.

s: a set with a default argument set() (an empty set).

So s=set() is created only once and reused in all future calls unless a different s is passed.

Line 2: Add to the Set

    s.add(val)

Adds the given val to the set s.

Because s is reused, it remembers previous values added in earlier calls.

Line 3: Return the Set

    return s

Returns the modified set s.

Line 4: First Call

print(tricky(1))

tricky(1) is called.

Since no second argument is given, it uses the default set.

1 is added to the set.

The set becomes: {1}

Output: {1}

 Line 5: Second Call

print(tricky(2))

tricky(2) is called.

Uses the same default set as before (shared between calls).

Adds 2 to that set.

Now the set is: {1, 2}

Output: {1, 2}

Line 6: Third Call

print(tricky(1))

tricky(1) is called again.

Still using the same set {1, 2}.

1 is already in the set, so adding it again has no effect.

Set remains: {1, 2}

Output: {1, 2}

Final Output

{1}

{1, 2}

{1, 2}

Python Coding challenge - Day 509| What is the output of the following Python Code?

 Code Explanation:

1. Function Definition

def func(a, b=[]):

Defines a function func with two parameters:

a: required argument.

b: optional argument with a default value of an empty list [].

Important: Default parameter values are evaluated once when the function is defined, so the same list b is used across calls unless explicitly overridden.

2. Append a to List b

b.append(a)

Adds the value of a to the list b.

Since b is mutable (a list), this modifies the list in place.

3. Return the List b

return b

Returns the modified list b.

4. First Call: func(1)

print(func(1))

Calls func with a=1.

Since b is not provided, it uses the default list [].

1 is appended to the list → list becomes [1].

Returns [1].

Output: [1]

5. Second Call: func(2)

print(func(2))

Calls func with a=2.

No b provided, so it uses the same default list as before (which already contains [1]).

2 is appended → list becomes [1, 2].

Returns [1, 2].

Output: [1, 2]

6. Third Call: func(3, [])

print(func(3, []))

Calls func with a=3 and explicitly passes a new empty list [] as b.

3 is appended to this new list → [3].

Returns [3].

The default list remains unchanged as this call used a fresh list.

Output: [3]

7. Fourth Call: func(4)

print(func(4))

Calls func with a=4 and no b, so it uses the default list again.

The default list currently is [1, 2] from previous calls.

4 is appended → list becomes [1, 2, 4].

Returns [1, 2, 4].

Output: [1, 2, 4]

Final Output:

[1][1, 2][3][1, 2, 4]

Building Agentic AI Systems: Create intelligent, autonomous AI agents that can reason, plan, and adapt

 

Building Agentic AI Systems – A Blueprint for the Future of Autonomous Intelligence

"What if AI could act—not just answer? Think, plan, and improve—not just predict? Building Agentic AI Systems shows you how to make that leap."

Overview

Building Agentic AI Systems is not just a technical manual—it's a manifesto for the future of intelligent machines. As we enter the post-LLM (large language model) era, the focus is shifting from passive models to autonomous agents: systems that can reason about the world, plan over time, take initiative, and learn from experience.

This book serves as a comprehensive guide to designing, building, and deploying AI agents that are not just reactive, but proactive—capable of decision-making, tool use, and adaptive behavior in complex environments.

 What Are Agentic AI Systems?

Agentic AI refers to AI systems that operate with a degree of autonomy, often with these four core capabilities:

Reasoning – The ability to evaluate options and make inferences.

Planning – Creating a sequence of actions to achieve long-term goals.

Tool Use – Calling external resources (e.g., APIs, search engines, code compilers).

Adaptation – Learning from feedback and adjusting behavior.

Think of tools like AutoGPT, OpenAI Agents, LangChain, or multi-agent ecosystems that complete tasks without needing step-by-step instructions. This book is a deep dive into the theory and engineering behind them.

What You’ll Learn

Each chapter is crafted with a blend of foundational theory, implementation strategies, and real-world use cases. Here's a breakdown of the key takeaways:

Chapter 1: The Rise of Agency in AI

Why traditional ML is not enough.

Key concepts: autonomy, intentionality, embodiment, alignment.

Historical context from GOFAI to LLM-driven agents.

Chapter 2: Architecting Autonomous Agents

Agent loop: Observe → Think → Act → Reflect.

Architectures: ReAct, Reflexion, CAMEL, AutoGPT.

Memory models: episodic, semantic, and working memory.

Chapter 3: Reasoning and Planning

Rule-based vs. probabilistic reasoning.

Classical planning (STRIPS, PDDL) vs. LLM-driven chaining.

Long-term planning with vector databases and recursive thinking.

Chapter 4: Tool Use and Environment Interaction

Calling APIs, using plugins, and executing code.

Toolformer-style fine-tuning and retrieval-augmented generation.

Integrating browser, file, and coding tools for enhanced cognition.

Chapter 5: Multi-Agent Collaboration

Building swarms, teams, and societies of agents.

Communication protocols and coordination strategies.

Use cases in simulations, games, research, and logistics.

Chapter 6: Feedback, Learning, and Safety

Online learning and continual improvement.

Reward shaping, human-in-the-loop supervision, and safe exploration.

Ethical design and alignment challenges.

Practical Projects in the Book

The book doesn’t just describe—it teaches by doing. You’ll build:

AutoResearcher – A multi-agent system that autonomously explores scientific questions using live data.

TaskCommander – An LLM-powered task agent that can manage your calendar, write emails, and retrieve documents.

CodeArchitect – An AI engineer that builds, tests, and refactors software components.

Simulife – A virtual city populated with AI agents driven by goals, memory, and personality.

Each project includes step-by-step walkthroughs, code snippets (Python + LangChain/OpenAI), and prompts for customization.

Why This Book Matters

The shift toward agentic AI mirrors a broader trend in computing: moving from tools that serve us when asked, to partners that act on our behalf.

This book is a playbook for future-ready AI engineers. As models become cheaper and more powerful, the value will move up the stack—to systems that are persistent, adaptive, and agentive.

Whether you want to build AI co-workers, autonomous researchers, or digital products that think for themselves, this book gives you the framework, tools, and mindset to get started.

Who Should Read This?

AI Practitioners who want to go beyond model training and into full-system design.

Software Developers exploring autonomous workflows and intelligent agents.

Product Managers building AI-native platforms and apps.

Researchers and Students studying cognitive science, reinforcement learning, or artificial general intelligence.

Python Coding challenge - Day 508| What is the output of the following Python Code?

 

  Code Explanation:

1. Creating a generator expression

x = (i*i for i in range(3))

Explanation:

Creates a generator x that will yield squares of numbers 0, 1, and 2 (i.e., 0, 1, 4).

The generator is lazy — it doesn’t calculate anything until you ask for values.

Output:

None

2. Getting the first value from the generator

print(next(x))

Explanation:

Calls next(x) to get the first value from the generator.

3. Getting the second value from the generator

print(next(x))

Explanation:

Calls next(x) again.

4. Recreating the generator expression (resetting)

x = (i*i for i in range(3))

Explanation:

Assigns a new generator to x.

This resets the sequence back to start from 0 again.

Output:

None

5. Getting the first value from the new generator

print(next(x))

Explanation:

Calls next(x) on the new generator.

Final Output:

0

1

0

Python Coding challenge - Day 505| What is the output of the following Python Code?

 

Code Explanation:

1. import math

Purpose: Imports the built-in Python math module, which contains mathematical functions, including sqrt (square root).

Effect: Allows you to use math.sqrt() to calculate square roots.

2. numbers = [4, 9, 16]

Purpose: Defines a list called numbers containing three integers.

Effect: This list is the input data that will be processed by the functions below.

3. def f(x):

Purpose: Defines a function named f that takes one argument x.

Effect: Prepares a function that can be called with a value to perform some operation (defined in the next line).

4. return round(x, 1)

Purpose: Inside function f, returns the value of x rounded to 1 decimal place.

Effect: This ensures the final output is a float rounded to one decimal digit.

5. def g(lst):

Purpose: Defines a function named g that takes one argument lst (expected to be a list).

Effect: Prepares a function that will process the list and return a result.

6. return sum(map(math.sqrt, lst))

Purpose:

map(math.sqrt, lst) applies the math.sqrt function to each element in the list, producing their square roots.

sum(...) adds all those square roots together.

Effect: g(lst) returns the sum of the square roots of the numbers in the list.

7. print(f(g(numbers)))

Purpose: Calls function g on the list numbers, then passes the result to function f, and prints the final output.

Step-by-step:

g(numbers) computes sqrt(4) + sqrt(9) + sqrt(16) → 2 + 3 + 4 = 9.

f(9) rounds 9 to one decimal place → 9.0.

print() outputs 9.0 to the console.

Effect: Outputs the rounded sum of square roots of the list numbers.

Final Output:

Python Coding Challange - Question with Answer (01240525)

 

Step-by-Step Explanation:

1. person = "Bob"
   A variable person is assigned the string value "Bob".

2. Calling change_name(person)
   The function change_name is called with person as the argument. So inside the function, name becomes "Bob" (a copy of the string).

3. Inside change_name
   This line:

   
   name = "Alice"

   reassigns the local variable name to the string "Alice".
   However, this does not change the original variable person outside the function.

   • In Python, strings are immutable.

   • When you pass person to the function, you pass a copy of the reference to "Bob".

   • Reassigning name to "Alice" just makes the local variable name point to a different string.

   • The original person variable still points to "Bob".

4. print(person)
   This prints "Bob" because the original person was never changed outside the function.

---

✅ Final Output:

Bob

---

 Key Concept:

In Python, immutable types like strings cannot be changed in-place.
Reassigning a function argument only affects the local copy, not the original variable.
