Say I have a list like ltrs and I want to print out all the possible 3
letter combinations. I want to combine letters from each inner list but
not combine any letters within the inner list itself. So ACF and ADF
would be ok but ABC would not.
I can lay it out manually and see the pattern, I cannot figure out how
to do it programically. Just in case this looks like homework it is not.
It's a small test case I devised to try to figure it out so I can apply
it to a bigger real world problem I am working on.
ltrs = [['A', 'B'], ['C', 'D', 'E'], ['F', 'G', 'H', 'I']]
print(ltrs[0][0]+ltrs[1][0]+ltrs[2][0]) #ACF
print(ltrs[0][0]+ltrs[1][1]+ltrs[2][0]) #ADF
print(ltrs[0][0]+ltrs[1][2]+ltrs[2][0]) #AEF
print(ltrs[0][0]+ltrs[1][0]+ltrs[2][1]) #ACG
print(ltrs[0][0]+ltrs[1][1]+ltrs[2][1]) #ADG
print(ltrs[0][0]+ltrs[1][2]+ltrs[2][1]) #AEG
.
.
.
print(ltrs[0][1]+ltrs[1][2]+ltrs[2][3]) #BEI
thanks, Jim
