Movie-like password cracking animation in Python that looks nifty. Code for guessing a string written for a problem in "Problem Solving with Algorithms and Data Structures" with my additional idea of printing every attempt and slowing down prints to make them readable. Tested with Python 2.7/3.4.

password_animation.py

from __future__ import print_function, unicode_literals
import random
import time


def generate_random_guess(chars):
    return random.choice(chars)


def repeated_guesses(target):
    chars = 'abcdefghijklmnopqrstuvwxyz '
    current_guess = len(target) * ['*']
    for count, char in enumerate(target):
        while current_guess[count] != char:
            current_guess[count] = generate_random_guess(chars)
            print(''.join(current_guess))
            # slight pause to make readable
            time.sleep(0.015)


def main():
    target = "methinks it is like a weasel"
    repeated_guesses(target)


if __name__ == '__main__':
    main()

Please check out my edit
Thanks for the script. I've edited it to make it more "hollywood" like. I used sys.stdout.flush(), sys.stdout.write() and \r carriage return.
