List comprehensions are one of Python’s most loved features for a good reason: they allow you to create lists in a clean, concise way. Instead of using loops, you can build lists with just a single line of code.

🔹 Basic Syntax:

A list comprehension is structured as follows:

[expression for item in iterable if condition]

This single line will replace many lines of traditional looping. Here’s an example:

# Using a for loop
squares = []
for x in range(10):
    squares.append(x**2)

# Using a list comprehension
squares = [x**2 for x in range(10)]
print(squares)  # Output: [0, 1, 4, 9, 16, 25, 36, 49, 64, 81]

With list comprehensions, the code is cleaner and often more readable!

🔹 Filtering with Conditions:

You can add a condition to filter items as they’re added:

# Only even squares
even_squares = [x**2 for x in range(10) if x % 2 == 0]
print(even_squares)  # Output: [0, 4, 16, 36, 64]

🔹 Benefits:

1. Conciseness: Shorten your code.
2. Readability: Makes your intent clear at a glance.
