List Comprehension in Python

List comprehension in Python is a concise way to create lists. It allows you to generate a new list by applying an expression to each item in an existing list or iterable, often using a for-loop and optional conditionals, all in a single line of code.

Here's a simple example:

# Traditional way
squares = []
for x in range(10):
    squares.append(x**2)

# List comprehension way
squares = [x**2 for x in range(10)]
print(squares)

result:

Python List Comprehension Syntax:

• expression: The value to include in the new list.

• item: The variable representing each element in the iterable.

• iterable: The collection of items you are looping through.

• condition (optional): A filter that determines which items to include.

returns: a new list that is created based on the specified expression, for each item in the given iterable, and optionally filtered by a condition.
