Python Mastermind Game Troubles

Question

I\'m a beginner to Python programming and have come upon an issue with my current assignment. The assignment reads as follows...

• Your program should secretly g

Answer 1

Here is an example that uses some more advance python idioms to improve readability and succinctness. This also makes it easier to make a more general solution such as for n digit answers for m base.

import random
from itertools import permutations   # for "lucky guess" Easter egg

def main(base=10, size=4):
    print 'New game started.\nGood luck!\n'
    answer, turn = list(genAnswer(range(base), size)), 1
    while True:
        hint = ['X' if a == g 
           else '0' if g in answer
           else '-' for a, g in zip(answer, guess(base, size))]
        if set(hint) == set(['X']):
            if turn == 1:
                choices = len(list(permutations(range(base), size)))
                print 'You won, lucky guess out of %d possible choices' % choices
            else:
                print 'Congratulations, you won in %d turns!' % turn
            return
        print '  Hint %d: %s' % (turn, ''.join(hint))
        turn += 1

def genAnswer(digits, size):
    '''Python generator function'''
    for i in range(size):
        choice = random.choice(digits)
        yield str(choice)
        digits.remove(choice)

def guess(base, size):
    '''Uses duck typing for error detection'''
    while True:
        guess = raw_input('>> Guess: ').strip()
        try:
            if int(guess, base) < base**size and len(set(guess)) == size:
                return guess
        except ValueError:
            pass
        print 'Enter %d unique digits from 0 to %d' % (size, base -1)

>>> main(6, 4)
New game started.
Good luck!

>> Guess: 1234
  Hint 1: 0-X-
>> Guess: 12345
Enter 4 unique digits from 0 to 5
>> Guess: 01227
Enter 4 unique digits from 0 to 5
>> Guess: 0123
  Hint 2: XX-0
>> Guess: 0135
Congratulations, you won in 3 turns!
