did you try it?

>>> keys = ('foo', 'bar')
>>> values = (1, 2)
>>> dict = {}
>>> for key, value in keys, values:
...     dict[key] = value
...
>>> assert dict == {'foo': 1, 'bar': 2}
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
AssertionError
>>> dict
{'foo': 'bar', 1: 2}

it's a 2.0 thing:

>>> 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.
