Suppose I have two differently-sized lists
a = [1, 2, 3]
b = ['a', 'b']
What is a Pythonic way to get a list of tuples c of all the possible combinations of one element from a and one element from b?
>>> print c
[(1, 'a'), (1, 'b'), (2, 'a'), (2, 'b'), (3, 'a'), (3, 'b')]
The order of elements in c does not matter.
The solution with two for loops is trivial, but it doesn’t seem particularly Pythonic.
Try
itertools.product.
