You don't even need the loop, just the zip.

>>> from collections import OrderedDict
>>> OrderedDict(zip([5, 9, 3, 53, 2342, 'pizza'], 'abcdef'))
OrderedDict([(5, 'a'), (9, 'b'), (3, 'c'), (53, 'd'), (2342, 'e'),
('pizza', 'f')])

But it's probably more readable as
>>> keys = [5, 9, 3, 53, 2342, 'pizza']
>>> values = 'abcdef'
>>> OrderedDict(zip(keys, values))
OrderedDict([(5, 'a'), (9, 'b'), (3, 'c'), (53, 'd'), (2342, 'e'),
('pizza', 'f')])
