Python Coding challenge - Day 576| What is the output of the following Python Code?

 

Code Explanation:

1. Initialization of a List

funcs = []

Here, an empty list funcs is created.

This list will be used to store functions.

2. Start of a For Loop

for i in range(3):

This line begins a loop that will run 3 times with i taking the values: 0, 1, and 2.

In each iteration, a function will be defined and added to the list funcs.

3. Definition of a Function with Default Argument

    def f(i=i):

        return i

A new function f is defined inside the loop.

Here's the key: i=i sets the default value of the parameter i to the current value of the loop variable.

This captures the current value of i at that iteration of the loop.

When the function f() is called without arguments, it returns this captured value.

4. Appending the Function to the List

    funcs.append(f)

The function f (defined above) is added to the list funcs.

After 3 iterations, funcs will contain 3 different functions, each with its own default value of i.

5. Calling All Stored Functions

print([f() for f in funcs])

This line creates a list comprehension.

It calls each function f() in the funcs list and collects their return values.

Since each function returns the value of i it captured during its definition, the output will be:

[0, 1, 2]

Final Output

[0, 1, 2]

Python Coding challenge - Day 577| What is the output of the following Python Code?

 

Code Explanation:

1. Function Definition

def mutate(x, y=[]):

This defines a function mutate with:

A required parameter x

An optional parameter y, which defaults to an empty list [].

Important: In Python, default mutable arguments like lists are shared between function calls unless explicitly overridden.

2. Append x to y

    y.append(x)

Appends the value of x to the list y.

If y is not passed in when calling the function, it uses the default list, which persists between calls.

3. Reassign y to a New List

    y = []

This line reassigns the local variable y to a brand new empty list, but:

This does not affect the original list that y.append(x) modified.

The mutation (append) happened on the shared default list, but this reassignment is just local and temporary.

4. Return y

    return y

Returns the new empty list that was just created.

So, it always returns [], regardless of what was appended earlier.

Print Statements

First Call

print(mutate(1))  # y = [], then y.append(1), then y = [], return []

Appends 1 to the default list (y becomes [1])

Then reassigns y to a new list [] and returns it.

Output: []

Second Call

print(mutate(2))  # y still holds the earlier appended value: [1]

Now the default list y is already [1] from the previous call.

Appends 2, so default y becomes [1, 2]

Again, reassigns y = [] and returns it.

Output: []

Final Output

[]

[]

Introduction to Large Language Models

 

 Introduction

Artificial intelligence is rapidly transforming the world, and at the center of this revolution are Large Language Models (LLMs). The course “Introduction to Large Language Models” is designed to provide learners — especially those without a deep technical background — with a foundational understanding of how these powerful models work, what they can do, and how to use them responsibly. Whether you're a developer, product manager, or AI enthusiast, this course serves as a critical stepping stone into the world of AI-driven language technologies.

What Are Large Language Models?

Large Language Models are deep learning models trained on massive amounts of text data to understand, generate, and interact in human-like language. They can write essays, answer questions, generate code, translate languages, and much more. Examples include OpenAI’s GPT models, Meta’s LLaMA, and Google’s Gemini. These models have billions (sometimes trillions) of parameters, allowing them to understand context, nuance, and structure in language at an unprecedented scale.

Why This Course Matters

While LLMs are becoming embedded in tools like chatbots, search engines, and writing assistants, very few people understand how they actually work. This course is essential for bridging that gap. It doesn't dive deep into math or code unless necessary — instead, it focuses on helping learners grasp how LLMs function, how they’re trained, and how they’re applied. With LLMs increasingly influencing business, media, education, and software development, this course equips professionals to engage with the technology intelligently and ethically.

Who Should Take This Course?

This course is ideal for a wide audience: students entering the field of AI, developers looking to build smarter applications, business leaders evaluating LLM use cases, and curious professionals who want to understand what’s behind tools like ChatGPT. You don’t need a background in machine learning to begin. A basic understanding of how software and the internet work will help, but the course is structured to bring all learners up to speed.

Learners understand the role of language modeling in AI and the importance of data and patterns in training such models.

b. Transformers and Attention Mechanisms

The transformer architecture is the engine behind modern LLMs. This module simplifies the complex concepts of self-attention, encoder-decoder models, and token embeddings. It also compares transformers with previous models like RNNs and LSTMs, helping learners appreciate why transformers are more effective and scalable.

c. Training and Fine-Tuning LLMs

Training an LLM requires massive data and compute power. This module breaks down the training pipeline — pretraining, fine-tuning, and transfer learning. It also introduces techniques like few-shot, zero-shot, and instruction tuning, and explains how developers can adapt open-source models to specific tasks or domains.

d. Prompt Engineering and Use Cases

One of the most exciting areas of working with LLMs is prompt engineering — crafting the right instructions to get the best results from a model. This module shows how to build prompts for summarization, translation, Q&A, creative writing, and more. It also introduces tools like OpenAI’s Playground and Hugging Face's Transformers for experimentation.

e. Limitations, Ethics, and Responsible AI

This critical section explores the ethical and social implications of LLMs. Topics include bias in training data, model hallucination, privacy risks, and the importance of responsible AI governance. Learners come away with a balanced view of both the power and limitations of LLMs.

Learning Outcomes

By the end of the course, learners will be able to:

• Explain what large language models are and how they function.

• isinstance(object, classinfo) is a built-in function that checks if an object is an instance of a specific class or a subclass.

• It returns:

  • True → if the object is an instance of the class

  • False → if it's not

---

In This Case

• 3.5 is a floating-point number

• int refers to the integer data type

So, Python checks:

Is 3.5 an instance of int?

No, it’s an instance of float.

---

Python Coding challenge - Day 574| What is the output of the following Python Code?

 

Code Explanation:

 Function Definition

def func(a, b=None):

func is defined with:

a: required argument

b: optional argument with a default value of None

This is a safe pattern to avoid the mutable default argument trap.

Check if b is None

    if b is None:

        b = []

If the caller did not provide a list (b is None), then it creates a new list.

Append a to b

    b.append(a)

Adds the value a to the list b.

Return b

   return b

Returns the modified list.

Function Calls

Call 1:

x = func(1)

b is not passed → None

Creates a new list → b = []

Appends 1 → b = [1]

Returns [1], so x = [1]

Call 2:

x = func(2)

Again, b is not passed → None

Creates a new list again

Appends 2 → b = [2]

Returns [2], so x = [2] (overwrites previous value)

Final Output:

print(x)

Prints the most recent value of x, which is [2]

Final Output:

[2]

Python Coding challenge - Day 575| What is the output of the following Python Code?

 

Code Explanation:

Function Definition

def f(x, y=[]):

    for i in range(x):

        y.append(i)

    return y

Parameters:

x: How many numbers to append (from 0 to x-1)

y: A list to which numbers will be appended. Default is a mutable list []

Function Calls

Call 1:

print(f(2))

x = 2, y not passed → uses shared default list.

Loop appends 0, 1 → y = [0, 1]

Returns: [0, 1]

Call 2:

print(f(3, []))

x = 3, y = [] → a new list is passed explicitly.

Loop appends 0, 1, 2 → y = [0, 1, 2]

Returns: [0, 1, 2]

This one is isolated from the shared default list.

Call 3:

print(f(2))

x = 2, y not passed → again uses the shared default list, which already contains [0, 1] from Call 1.

Appends 0, 1 again → y = [0, 1, 0, 1]

Returns: [0, 1, 0, 1]

Final Output:

[0, 1]

[0, 1, 2]

[0, 1, 0, 1]

Python Coding challenge - Day 572| What is the output of the following Python Code?

 

Code Explanation:

1. Function Definition

def add_to(val, lst=None):

def: This keyword starts the definition of a function named add_to.

val: This is the value you want to add to a list.

lst=None: This is an optional parameter. If no list is passed, it defaults to None.

2. Handling Default Argument

    if lst is None:

        lst = []

Checks if lst is None (which it is if not explicitly passed).

If lst is None, a new empty list is created: lst = [].

This is a common Python idiom to avoid using a mutable default argument (like []), which can lead to bugs.

3. Appending the Value

    lst.append(val)

Adds the value of val to the end of the list lst.

4. Returning the List

    return lst

Returns the modified list with the new value added.

5. Function Calls & Print

print(add_to(3), add_to(5))

add_to(3): Since no list is passed, lst is None, so a new list is created: [] → [3]. Returns [3].

add_to(5): Again, no list is passed, so a new list is created: [] → [5]. Returns [5].

print([3], [5]) will output:

[3] [5]

Final Output:

[3] [5]

Python Coding challenge - Day 573| What is the output of the following Python Code?

 

Code Explanation:

1. Function Definition

def tricky(val, result=[]):

Defines a function tricky with:

val: the value to add to a list.

result=[]: a default argument that is a mutable list.

2. Appending to the List

    result += [val]

result += [val] is equivalent to result.extend([val]).

It modifies the list in place, rather than creating a new list.

3. Return Statement

    return result

Returns the modified result list.

4. Function Calls & Output

print(tricky(1))

First call: val=1, result=[] (default list used).

result += [1] → result becomes [1].

Returns: [1].

print(tricky(2))

Second call: val=2, result is still the same list used in the first call ([1]).

result += [2] → result becomes [1, 2].

Returns: [1, 2].

print(tricky(3, []))

This time, a new list is passed explicitly as result=[].

result += [3] → becomes [3].

Returns: [3].

print(tricky(4))

Again, uses the original default list, which was mutated to [1, 2].

result += [4] → becomes [1, 2, 4].

Returns: [1, 2, 4].

Final Output

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

Python Coding Challange - Question with Answer (01260625)

 

s.find("z") – What does it do?

The .find() method in Python is used to search for a substring in a string.
It returns:

• The index of the first occurrence of the substring if found.

• -1 if the substring is not found.

---

 In this case:

s = "python"
s.find("z") # Looking for the letter 'z' in the string "python"

• The string "python" does not contain the letter "z".

• So, .find("z") returns **-1**.

---

✅ Final Output:

-1

 Summary:

• .find("z") didn’t find 'z' in 'python'.

• It returned -1 to indicate "not found."
