How can I write a loop using letters instead of numbers so it looks like this:
2 sets used 'a-z' and 'A-Z'
aaaaa
aaaaA
aaaAa
aaAaa
and so on:
aaaAA
then on to b:
bbbbb
bbbbA
I can do it with numbers, something like this:
for i in range(10):
for j in range(10):
for k in range(10):
print i,j,k
How does this work with letters?
