Extract same elements from two lists

Question

Given two lists

a = [1,2,3,4,5]
b = [2,4,6,7]

output similar element

c = [2,4]

Is there API to compare and extract similar elements from two lists? It could be possible to do it by compare element by element, but I am wondering if there are already API.

Another option would be to make some effort and search for the numerous solutions that would be available. — devnull, Jun 04 '14 at 13:11
@devnull: Then at least call it `set` (lowercase) for the built-in type. — Martijn Pieters, Jun 04 '14 at 13:13
@MartijnPieters My bad! Now this does deserve a few answers. — devnull, Jun 04 '14 at 13:15

print set(a).intersection(set(b))

use intersection to get common elements in the both list
