List comprehensions in Python

List comprehensions are a concise way to create a list in Python. They are written as a single line of code and are easy to read and understand.

Here’s the general syntax for a list comprehension:

[expression for item in iterable if condition]

The expression is the result that you want to add to the list, item is a variable that takes on each value in the iterable, and condition is an optional test that determines whether the value should be added to the list.

Here’s an example of a list comprehension that creates a list of the squares of the numbers from 1 to 10

squared_numbers = [x**2 for x in range(1, 11)]

This code is

squared_numbers = []
for x in range(1, 11):
    squared_numbers.append(x**2)

List comprehensions are often faster and more concise than traditional for loops and can simplify your code.
