Google "python list comprehension".
If Google is broken for you, try Yahoo, or any other search engine.

Instead of this:
L = []
for x in range(10):
L.append(x**2)
you can write:
L = [x**2 for x in range(10)]
Instead of this example:
L = []
for x in range(10):
if x % 2 == 0:
L.append(x**2)
you can write:
L = [x**2 for x in range(10) if x % 2 == 0]
