Combining Multiple Sets of Letters in Python

Question

I am trying to figure out how to print all the combinations there are for multiple sets of letters without repetition.

An example: A,B,C and X,Y,Z

The combinations would be:

AX AY AZ BX BY BZ CX CY CZ

Answer 1

You can use itertools.product to get what you want.

from itertools import product
a = ['A', 'B', 'C']
b = ['X', 'Y', 'Z']

for i in product(a, b):
    print ''.join(i)

Answer 2

You could just loop over both sets:

for a in abcstring:
    for x in xyzstring:
        print a + x
