Password Brute Force

[2skywalkers]

Im trying to make a password Brute Force, it works to an extent but there is a problem.

Its goes from 'az' to 'bb' instead of 'ba'

Same with 'aaz' to 'abb' instead of 'aba'

Im not sure if im doing this password guesser completely wrong because it seems to simple, if so tell me please. i asked on another post how to do it, looked around for a few hours and still could not figure it out.

from itertools import combinations_with_replacement

for item in combinations_with_replacement('abcdefghijklmnopqrstuvwxyz', 1):
    print(''.join(item))
    
for item in combinations_with_replacement('abcdefghijklmnopqrstuvwxyz', 2):
    print(''.join(item))
    
for item in combinations_with_replacement('abcdefghijklmnopqrstuvwxyz', 3):
    print(''.join(item))
