摇滚，纸张和剪刀python程序与累加器

Question

我正在尝试用累加器编写一个用于摇滚，纸张和剪刀的python程序，我无法弄清楚如何使累加器工作。这是我的代码。任何有关该问题的帮助将不胜感激。

import random

    player_wins = 0

Answer 1

您应该创建一个对象来保存您的分数，并determine_the_winner更新其字段：

import random

class Score:
    def __init__(self):
        self.total_games = 0
        self.ties = 0
        self.player_wins = 0
        self.computer_wins = 0

def main():
    score = Score()
    print "Welcome to rock, paper, and scissors."
    again = "y" 
    while again == "y":
        play_game(score)
        again = raw_input("Would you like to play again (y/n)? ")
    accumulator(score)

def get_computers_choice():
    return random.choice(["rock", "paper", "scissors"])

def get_players_choice():
    choices = {"1":"rock", "2":"paper", "3":"scissors"}

    while True:
        players_choice = raw_input("Enter 1 for rock, 2 for paper, or 3 for scissors: ")
        if players_choice in choices:
            return choices[players_choice]
        print "Error choice must be 1 for rock, 2 for paper, or 3 for scissors"

def play_game(score):    
    computers_choice = get_computers_choice()
    players_choice = get_players_choice()
    print "The player's choice is {choice}.".format(choice=players_choice)
    print "The computer's choice is {choice}.".format(choice=computers_choice)
    determine_the_winner(computers_choice, players_choice, score)

def determine_the_winner(computers_choice, players_choice, score):
    rules = [
        ('rock',     'crushes', 'scissors'),
        ('scissors', 'cuts',    'paper'),
        ('paper',    'covers',  'rock')
    ]

    score.total_games += 1

    for good, verbs, bad in rules:
        if computers_choice == good and players_choice == bad:
            outcome = "lose"
            score.computer_wins += 1
        elif players_choice == good and computers_choice == bad:
            outcome = "win"
            score.player_wins += 1
        else:

                                                            good=good,
                                                            verbs=verbs,
                                                            bad=bad)
        break
    else:
        score.ties += 1
        print("Game is a tie.")

def accumulator(score):
    print "You have played", score.total_games, "games"
    print "You won", score.player_wins, "games"
    print "You lost", score.computer_wins, "games"
