How to read this for loop program?

The below for loop doesn't have x**2 in its body which is generally Tab indented in the next line then how this program is able to generate output as given below:

>>> squares = [x**2 for x in range(10)]

Output: [0, 1, 4, 9, 16, 25, 36, 49, 64, 81]

if so then how should i read this for loop?

for x in range(10) simply means counting from 0-9. the list comprehension [x**2 for x in range(10)] then takes every value and squares it, and saves it in the list.

Look at this link: https://docs.python.org/2/tutorial/datastructures.html#list-comprehensions
