Python 2.7 quick reference

The purpose of this function is to build a list of tuples from two or more iterables of the same length. Here is the general form:

zip(S0, S1, S2, ...)

Each Si must be in iterable. The result is a list [T0, T1, ...], where each Ti is the tuple (S0[i], S1[i], S2[i], ...).

Here are some examples.

>>> L1=[1,2,3,4]
>>> L2=['a', 'b', 'c', 'd']
>>> zip(L1, L2)
[(1, 'a'), (2, 'b'), (3, 'c'), (4, 'd')]
>>> L3=[10.0, 20.0, 30.0, 40.0]
>>> zip(L1, L2, L3)
[(1, 'a', 10.0), (2, 'b', 20.0), (3, 'c', 30.0), (4, 'd', 40.0)]
