Python generate all possible strings of length n [duplicate]

Answer 1

Here's a piece of code that uses [Python 3.Docs]: itertools.product(*iterables, repeat=1).
Note that the number of generated strings is 62 ** length, so for testing purposes use small values for length:

import string
import itertools


def generate_strings(length=3):
    chars = string.ascii_letters + string.digits  # "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789"
    for item in itertools.product(chars, repeat=length):
        yield "".join(item)
