Combining two lists of strings together once in Python 3.4.3

I'm trying to combine a list of first- and surnames with no luck. My code is like this at the moment:

firstname=['Tom','Dick','Steve']
surname=['Johnson','Smith','Doe']
for f in (firstname):
    for s in (surname):
        print(f,s)

Which gives me something like this:

Tom Johnson
Tom Smith
Tom Doe
Dick Johnson

And so on, when I really want:

Tom Johnson
Dick Smith
Steve Doe

Help much appreciated for a beginner like me.

firstname=['Tom','Dick','Steve']
surname=['Johnson','Smith','Doe']
i = 0
while i<min(len(firstname), len(surname)):
    print (firstname[i], surname[j])
    i += 1

Zip is the way to combine two lists together in python. So, as a function,

def combine_names(first, last):
    comb = zip(first, last)
    for f,l in comb:
        print f,l

Assuming both lists have the same length, you could iterate over it and use the corresponding index on both:

for i in range(len(firstname)):
    print (firstname[i], surname[i])
