A simple and practical formula for listing in Python

A list derivation is a way to create a new list with another list that works like A For loop:
>>> [x*x for X in range (10)]
[0, 1, 4, 9, 16, 25, 36, 49, 64, 81]
The list consists of the square of each x in range (10), and if you want to print only the squares that are divisible by 3? Then you can use the modulo operator--x%3, which returns 0 when the number can be divisible by 3:
>>> [x*x for x in range (ten) if x%3==0]
[0, 9, 36, 81]
You can also add more parts of the FOR statement:
>>> [(x, Y) for x in range (3) for Y in range (3)]
[(0, 0), (0, 1), (0, 2), (1, 0), (1, 1), (1, 2), (2, 0), (2, 1)]


>>> x=[' waking ', ' in ', ' the ', ' Sun ']
>>> y=[' Today ', ' before ', ' silence '
>>> [B + ' + ' +g for B in X for G in Y if b[0]==g[0]]
[' The+today ', ' sun+silence ']
