`string.digits`

) and lower case letters (`string.ascii_lowercase`

).

## Method 1

Here’s a naiive brute force method that will guess numbers (`string.digits`

) and lower case letters (`string.ascii_lowercase`

). You can use `itertools.product`

with `repeat`

set to the current password length guessed. You can start at `1`

character passwords (or whatever your lower bound is) then cap it at a maximum length too. Then just `return`

when you find the match.

import itertools import string def guess_password(real): chars = string.ascii_lowercase + string.digits attempts = 0 for password_length in range(1, 9): for guess in itertools.product(chars, repeat=password_length): attempts += 1 guess = ''.join(guess) if guess == real: return 'password is {}. found in {} guesses.'.format(guess, attempts) # uncomment to display attempts, though will be slower #print(guess, attempts) print(guess_password('abc'))

Output

a 1 b 2 c 3 d 4 ... aba 1369 abb 1370 password is abc. found in 1371 guesses.

## Method 2

One possible option which would preserve almost exactly your current code is to convert to base 36 with the following “digits”: `0-9a-z`

. This will give you every possible alpha-numeric combination for n characters if you search in `range(36**n)`

.

def baseN(num, b=36, numerals="0123456789abcdefghijklmnopqrstuvwxyz"): return ((num == 0) and numerals[0]) or (baseN(num // b, b, numerals).lstrip(numerals[0]) + numerals[num % b])

You can then loop through numbers as in your example:

>>> for i in range(10000, 10005): ... print(baseN(i).zfill(5)) ... 007ps 007pt 007pu 007pv 007pw

To get all 3-letter possibilities, you can loop as follows:

for i in range(36**3): possible = baseN(i).zfill(3)
