All lists where each element can change from 0 to a

Assume we are given two positive integers a and b. We want to know all possible all possible lists of size b where each element can be from 0 to a (not including a).

For example if a =2, b=2, we should have [0,0],[0,1], [1,0],[1,1].

Is there any way for having all such lists with Standard python functions?

With itertools this is a snap. Does that count as standard python? – John Coleman Apr 11 '17 at 20:59

@JohnColeman Preferably, without itertools. – m0_as Apr 11 '17 at 21:03

You can roll your own recursive solution, but it is literally 1-line with itertools: `[list(p) for p in itertools.product(range(a),repeat=b)]` – John Coleman Apr 11 '17 at 21:05
