Day 3 solution for Advent of Code 2016 as it was when I submitted my answer

from hashlib import md5

secret = 'reyedfim'
nonce = 0
digits = []
passwd = [None] * 8

while not all(passwd):
    hash = md5()
    hash.update('{}{}'.format(secret, nonce).encode('utf-8'))
    hex = hash.hexdigest()
    # print(hex)
    # print(hex[:5])
    if hex[:5] == '00000':
        # print(hex[5])
        digits.append(hex[5])
        pos = hex[5]
        char = hex[6]
        print(pos, char)
        print(pos.isdigit())

        if pos.isdigit() and 0 <= int(pos) < 8 and passwd[int(pos)] is None:
            passwd[int(pos)] = char
            print(passwd)
    nonce += 1

print(''.join(digits))
print(passwd)
