🎯 Python Quick Quiz – OOP Edition
💡 _What is the primary use of the __init__ method in a Python class?_

🔘 Option 1: Initializing class attributes
🔘 Option 2: Defining class methods
🔘 Option 3: Inheriting from a superclass
🔘 Option 4: Handling exceptions

🧠 Correct Answer: Option 1
📌 The init method is a special method used to initialize the object’s attributes when a class is instantiated. It's like a constructor in other programming languages.
class Person:
def __init__(self, name, age):
self.name = name
self.age = age

john = Person("John", 25)
print(john.name) # Output: John

🧠 Quiz: What is the most "Pythonic" way to create a new list containing the squares of numbers from an existing list called nums?

A) Using a for loop and the .append() method.
B) new_list = [num**2 for num in nums]
C) Using a while loop with an index counter.
D) new_list = (num**2 for num in nums)

Correct answer: B

Explanation: This is a list comprehension. It's a concise, readable, and often faster way to create a new list from an iterable compared to a traditional for loop. Option D creates a generator expression, not a list.
