ltrs = [['A', 'B'], ['C', 'D', 'E'], ['F', 'G', 'H', 'I']]

A fairly straightforward way is to use nested loops:

for l in ltrs[0]:
...   for j in ltrs[1]:
...     for k in ltrs[2]:
...       print l,j,k

Sorry, let’s try to make that a little cleaner-looking

for x in ltrs[0]:
   for y in ltrs[1]:
     for z in ltrs[2]:
       print x,y,z

Seeing it in front of me it does look straight forward, I was having difficulty visualizing how to solve it.

thanks, Jim
