So, what do you think? Is this a common enough need that it should be built into itertools? The main namespace? Or should we leave it out, since adding it would encourage people writing O(n^x) algorithms? If nothing else, list members can enjoy rewriting this function for fun.
It is already in itertools:

from itertools import product for v in product(*[[True, False]]*3): ... print(v) ... (True, True, True) (True, True, False) (True, False, True) (True, False, False) (False, True, True) (False, True, False) (False, False, True) (False, False, False)
Or a bit more readable:
for v in product([True, False], repeat=3): ... print(v)
