python 2.7.11 docs: "The returned list is truncated in length to the
length of the shortest argument sequence."
a = ['who','let','the']
b = ['dogs','out?']
c = zip(a,b)
print c
[('who', 'dogs'), ('let', 'out?')]
Wouldn't it be better to return an empty element than silently kill your
data?
[('who', 'dogs'), ('let', 'out?'), ('the', '')]
Edit: I see they addressed this in 3.5 (maybe earlier), with an option:
"itertools.zip_longest(*iterables, fillvalue=None)
Make an iterator that aggregates elements from each of the iterables. If
the iterables are of uneven length, missing values are filled-in with
fillvalue. Iteration continues until the longest iterable is exhausted."
