Answer 1

You can iterate over the product of all of them. Use itertools.product and pass in your ranges.

import itertools
for i in itertools.product(range(2), range(3), range(2)):
print (i)

yields

(0, 0, 0)
(0, 0, 1)
(0, 1, 0)
(0, 1, 1)
(0, 2, 0)
(0, 2, 1)
(1, 0, 0)
(1, 0, 1)
(1, 1, 0)
(1, 1, 1) 
(1, 2, 0)
(1, 2, 1)
