[Tutor] The game of nim in python

[Michael Selik]

What's the problem you're trying to solve? Did you get an error?

Here's a quick revision. There's probably a more elegant way, but this
seems to work.

    #/usr/bin/env python

    from __future__ import print_function
    import random

    try:
        input = raw_input
    except NameError:
        pass # already using Python 3


    player = input('Enter your name: ')

    straws = random.randint(10, 20)
    if straws % 4 == 1:
        straws += 1

    while straws:
        print("It's the Computer's turn. {} straws left.".format(straws))
        n = random.randint(1, min(3, straws))
        straws -= n
        print("The Computer removes {} straws.".format(n))

        if not straws:
            print("The Computer won!")
            break

        print("It's your turn, {}. There are {} straws
left.".format(player, straws))
        n = None
        while not n:
            print("You can remove between 1 and {} straws.".format(min(3,
straws)))
            try:
                n = int(input('How many straws do you want to remove? '))
                if n < 1 or n > min(3, straws):
                    n = None
            except ValueError:
                pass
        straws -= n
        print("You removed {} straws.".format(n))

        if not straws:
            print("You won!")
            break
