* List Comprehensions in Python*

A list comprehension is a concise way to create lists by applying an expression to each item in an iterable.

*Basic Syntax* :

[expression for item in iterable if condition]


*Example 1: Square All Numbers*

nums = [1, 2, 3, 4]
squares = [x**2 for x in nums]
print(squares) Output: [1, 4, 9, 16]


*Example 2: Filter Even Numbers*

nums = [1, 2, 3, 4, 5, 6]
evens = [x for x in nums if x % 2 == 0]
print(evens) Output: [2, 4, 6]


*Example 3: Convert Strings to Uppercase*

names = [alice, bob, charlie]
upper_names = [name.upper() for name in names]
print(upper_names) Output: ['ALICE', 'BOB', 'CHARLIE']


*Equivalent Using Loops:*

squares = []
for x in nums:
squares.append(x**2)

List comprehensions are faster, cleaner, and more readable when used correctly.


*Mini Project: Filter Odd Numbers and Cube Them*


nums = list(range(1, 11))
odd_cubed = [x**3 for x in nums if x % 2 != 0]
print(Cubes of odd numbers from 1 to 10:, odd_cubed)


*This shows:*

- Filtering (odds only)

- Transformation (cubing)

- Compact, readable logic

please, bro, on example 1. ** stand for (power).? or.
