Help with this code

A for loop in Python is very simple:

for i in range(256):
    print(i)

The chr function will convert an int to str. Depending on the restrictions on your homework assignment you might want to look at the itertools module, or consider doing this with recursion (so you don't have to write out all of the loops).
