Iterate through a dictionary of lists one "line" at a time

[wswilson]

Here is my code:

listing = {'id': ['a', 'b', 'c'], 'name': ['Joe', 'Jane', 'Bob']}

I need to output:

id name
a Joe
b Jane
c Bob

I could do:

print 'id', 'name'
for id, name in zip(listing['id'], listing['name']): print id, name

but that only works if there are two entries in the dictionary, id and
name, and I know what they are. My problem is I don't know how many of
these entries there will be. Thanks for any help you can give!
