I need to do something for a science fair, and decided to find/modify/make a program to see how long it would take to "find" a password. After searching through the Internet, I found source code which I may use as inspiration to make my own program. However, I'm wondering if there was anything "wrong" or "slow" about this code. Also, I am failing to implement a system which can allow me to input the password that I wish to test (I'm an absolute beginner). So please, how can I make this code better, and how can I input a password to be cracked in the terminal? Sorry for any spelling mistakes, I'm not a native speaker.

Currently, to test for the password, I have to type in line 19 so the program knows if it is solved. As far as I can tell, this program uses the "Brute-Force" method in order to find a password. Also, just to be clear, this code is not originally mine. I believe this program is encoded with Python 2.

    import time

    import string



    maxattempts = 10000000000000000000

    start = time.time()

    chars = list(string.printable)[:95]

    base = len(chars)

    n = 0

    solved = False

    password = "ab" # This is where I put have to input the password.





    print chars



    # converts number N base 10 to a list of digits base b

    def numberToBase(n, b):

        digits = 

        while n:

            digits.append(int(n % b))

            n //= b

        return digits[::-1]





    # begin systematically checking passwords

    if not solved:

        while n < maxattempts:

            lst = numberToBase(n, base)

            print(lst)

            word = ''

            for x in lst:

                word += str(chars[x])

            print(word)

            if password == word:

                solved = True

                    print('-Stats-')

                    print('Pass: ' + word)

                    print('Attempts: ' + str(n))

                    print('time: ' + str((time.time() - start)) + ' sec')

                    break

                else:

                    n += 1



        # number of trys go over the attempt limit

        if not solved:

            print('Unsolved after ' + str(n) + ' attempts!')
