How can I iterate through two lists in Parallel

Question

I have two iterables, and I want to go over them in pairs

foo = (1, 2, 3)
bar = (4, 5, 6)

for (f, b) in some_iterator(foo, bar):
    print "f: ", f, "; b: ", b

The result should be

f: 1; b: 4
f: 2; b: 5
f: 3; b: 6

But that seems somewhat unpythonic to me. Is there a better way to do it?

Answer 1

You have to use the zip function for your cause

for (f,b) in zip(foo, bar):
    print "f: ", f ,"; b: ", b
