Python Coding challenge - Day 950| What is the output of the following Python Code?

 

Code Explanation:

1. Defining the Outer Function

def outer():

A function named outer is defined.

It will create and return another function.

2. Creating a Mutable Variable

    x = []

A list named x is created inside outer.

This list will be shared by the inner function through a closure.

3. Defining the Inner Function

    def inner():

        x.append(len(x))

        return x

inner is defined inside outer, so it captures x from the outer scope.

Every call to inner:

Computes len(x) (current length of the list),

Appends that value to x,

Returns the updated list.

4. Returning the Inner Function

    return inner

outer returns the inner function.

The returned function still has access to the list x because of the closure.

5. Creating the Closure

f = outer()

outer() is called once.

A new list x = [] is created.

inner is returned and assigned to f.

f now remembers and shares the same x across all calls.

6. Calling the Function Multiple Times

print(f(), f(), f())

Let’s evaluate each call:

▶ First f():

x = []

len(x) = 0, append 0 → x = [0]

Returns [0]

▶ Second f():

x = [0]

len(x) = 1, append 1 → x = [0, 1]

Returns [0, 1]

▶ Third f():

x = [0, 1]

len(x) = 2, append 2 → x = [0, 1, 2]

Returns [0, 1, 2]

7. Final Output

[0] [0, 1] [0, 1, 2]

Final Answer

✔ Output:

[0] [0, 1] [0, 1, 2]

Python Coding challenge - Day 949| What is the output of the following Python Code?

 

Code Explanation:

1. Defining a Custom Metaclass

class Meta(type):

Meta is a metaclass because it inherits from type.

A metaclass controls how classes are created.

2. Overriding the Metaclass __new__ Method

    def __new__(cls, name, bases, dct):

        dct["x"] = dct.get("x", 0) + 1

        return super().__new__(cls, name, bases, dct)

This method runs every time a class using this metaclass is created.

Parameters:

cls → the metaclass (Meta)

name → class name ("A", "B")

bases → parent classes

dct → dictionary of class attributes

What it does:

Looks for key "x" in the class dictionary.

If "x" exists, it takes its value; otherwise uses 0.

Adds 1 to it and stores it back as "x".

So the metaclass increments x by 1 during class creation.

3. Creating Class A

class A(metaclass=Meta):

    x = 5

What happens internally:

Class body executes: dct = {"x": 5}

Meta.__new__(Meta, "A", (), {"x": 5}) is called.

Inside __new__:

dct["x"] = 5 + 1 = 6

Class A is created with:

A.x = 6

4. Creating Class B

class B(A):

    pass

B inherits from A, so it also uses metaclass Meta.

Class body is empty: dct = {}

Meta.__new__(Meta, "B", (A,), {}) is called.

Inside __new__:

dct["x"] = 0 + 1 = 1

So B gets its own class attribute:

B.x = 1

5. Printing the Values
print(A.x, B.x)

A.x is 6

B.x is 1

6. Final Output

6 1

Python Coding challenge - Day 948| What is the output of the following Python Code?

 

Code Explanation:

1. Defining the Descriptor Class

class D:

A class named D is defined.

It will be used as a descriptor.

2. Implementing the __get__ Method

    def __get__(self, obj, owner):

        return 1

__get__ makes D a non-data descriptor (because it only defines __get__).

This method is called whenever the attribute is accessed.

It always returns 1.

3. Using the Descriptor in a Class

class A:

    x = D()

x is a class attribute managed by descriptor D.

Any access to x will trigger D.__get__.

4. Creating an Instance

a = A()

An object a of class A is created.

Initially:

a.__dict__ = {}

5. Assigning to a.x

a.x = 10

Since D does not implement __set__, assignment does not go through the descriptor.

Python stores the value directly in the instance dictionary:

a.__dict__["x"] = 10

6. Accessing a.x

print(a.x)

Here’s what Python does:

Looks for x on the class A and finds that it is a descriptor.

Calls:

D.__get__(D_instance, a, A)

__get__ returns 1.

The instance value a.__dict__["x"] is ignored.

7. Final Output

1

Final Answer

✔ Output:

1

def f(x, lst=[]):

A function f is defined with two parameters:

x → value to add

lst → a list with default value []

2. Appending to the List

    lst.append(x)

Appends the value x to the list lst.

3. Returning the List

    return lst

Returns the list after appending.

4. First Function Call

print(f(1))

What happens:

lst is the default list [].

1 is appended → [1].

The function returns [1].

Printed output:

[1]

Python Coding Challenge - Question with Answer (ID -060126)

 

Step-by-step Explanation

Line 1

lst = [1, 2, 3]

You create a list:

lst → [1, 2, 3]

---

Line 2

lst = lst.append(4)

This is the key tricky part.

• lst.append(4) modifies the list in-place

• But append() returns None

So this line becomes:

lst = None

Because:

lst.append(4) → None

The list is updated internally, but you overwrite lst with None.

---

Line 3

print(lst)

Since lst is now None, it prints:

None

---

✅ Final Output

None

---

 Why this happens

Function	Modifies list	Returns value
append()	Yes	None

So you should not assign it back.

---

✅ Correct way to do it

lst = [1, 2, 3]
lst.append(4)
print(lst)

Output:

[1, 2, 3, 4]

---

 Summary

• append() changes the list but returns None

• Writing lst = lst.append(4) replaces your list with None

• Always use lst.append(...) without assignment

Day 22 : Ignoring Traceback Messages

 

🐍 Python Mistakes Everyone Makes ❌

Day 22: Ignoring Traceback Messages

When your Python program crashes, the traceback is not noise — it’s your best debugging guide. Ignoring it slows you down and turns debugging into guesswork.

---

❌ The Mistake

print("Program crashed 😵")

Reacting to errors without reading the traceback means you’re missing critical information about what actually went wrong.

---

✅ The Correct Way

Traceback (most recent call last): 

File "app.py", line 5, in <module>

 print(numbers[5])

 IndexError: list index out of range

This message clearly tells you:

• What error occurred (IndexError)

• Where it happened (file name and line number)

• Why it happened (index out of range)

---

❌ Why Ignoring Tracebacks Fails

Tracebacks explain exactly what went wrong

• They show where the error occurred

• Ignoring them leads to guesswork debugging

• You miss valuable learning opportunities

---

🧠 Simple Rule to Remember

✔ Always read the full traceback
✔ Start from the last line (that’s the real error)
✔ Use it as your step-by-step debugging guide

---

🐍 Pro tip: The traceback is Python trying to help you don’t ignore it!

Applied Machine Learning with Python

 

Introduction

Machine learning (ML) is what powers everything from recommendation systems to fraud detection, from customer segmentation to predictive maintenance. But building ML solutions doesn’t just require math or theory — you need practical skills, know-how with real data, and fluency with tools. That’s where Applied Machine Learning with Python comes in: a course designed to teach you how to use Python, real datasets, and robust workflows to build ML models that actually work.

Rather than remain theoretical, this course emphasizes application — giving you a path from raw data to working models, from classification/clustering to predictions and insights.

Why This Course Matters

• Bridges theory and real-world use: Instead of just teaching abstract algorithms, it shows you how to apply ML methods (classification, clustering, regression) on real data — making your learning transferable to actual problems. 

• Wide range of ML techniques covered: From decision trees and random forests, to clustering and even semi-supervised methods — giving a broad foundation in commonly used algorithms. 

• Focus on practical workflow: Data preprocessing, feature engineering, model evaluation, boosting techniques — all the steps needed to build reliable ML models, not just prototypes. 

• Accessible to those with Python background: If you know basic Python and have some familiarity with data handling, you can pick this up — no need for deep theoretical math upfront. 

• Covers both supervised and unsupervised learning: Useful whether you have labelled data (for prediction) or unlabelled data (for clustering / exploration) — giving flexibility depending on the project.

What You Learn — Core Modules & Skills

The course is divided into modules that cover different parts of the ML pipeline and give you hands-on experience:

Introduction & Fundamentals of ML

• Understand the difference between traditional statistics and machine learning workflows — when and why you’d use ML.

• Learn basic evaluation metrics to assess models (accuracy, error, validation, etc.). 

Supervised Learning (Regression & Classification)

• Implement algorithms like decision trees, random forests, and other supervised methods to build predictive models. 

• Work through data preparation, feature engineering, training/testing splits — key practices that impact model performance.

• Learn techniques for improving model quality: tuning hyperparameters, boosting, cross-validation to avoid overfitting.

Unsupervised Learning & Clustering / Data Exploration

• Apply clustering algorithms (like K-means) to explore patterns in data when labels are unavailable. 

• Use ML to do segmentation, pattern detection, and exploratory data analysis — tasks often needed before deciding on a modeling approach. 

Building Complete ML Pipelines & Projects

• Combine data loading, preprocessing, modeling, evaluation — turning fragmented steps into coherent, reproducible workflows. 

• Learn to choose algorithms, preprocess data properly, interpret results — the sort of end-to-end skills needed in real-world ML work.
