for a in [True, False]: for b in [True, False]: for c in [True, False]: print a, b, c
Which yields

But if you don't know how many variables you'll have, you're stuck writing a complicated function instead of using a nice, simple for-loop.
So, going back to the first example, wouldn't it be nicer to write:
for x, y, z in combine(xs, ys, zs): #Do something
So, what do you think? Is this a common enough need that it should be built into itertools?
Presumably, since it has been added to itertools in 2.6 under the name product(). (Maybe Raymond borrowed the time machine?) :) Georg -- Thus spake the Lord: Thou shalt indent with four spaces. No more, no less. Four shall be the number of spaces thou shalt indent, and the number of thy indenting shall be four. Eight shalt thou not indent, nor either indent thou two, excepting that thou then proceed to four. Tabs are right out.
