>>> print zip.__doc__
zip(seq1 [, seq2 [...]]) -> [(seq1[0], seq2[0] ...), (...)]

Return a list of tuples, where each tuple contains the i-th element
from each of the argument sequences.  The returned list is truncated
in length to the length of the shortest argument sequence.
>>> zip(('a', 'b', 'c'), ('d', 'e', 'f'))
[('a', 'd'), ('b', 'e'), ('c', 'f')]
