我正在开发一个简单的石头剪刀布游戏。游戏运行正常，但有一个问题，当电脑的得分达到3分时，游戏不会停止。我不明白为什么，因为玩家的得分达到3分时游戏可以正常停止。请帮帮我！

from random import randintplayer_count = 0comp_count = 0def game():    player_choice = raw_input('Do you choose rock [r], paper [p], or scissors [s]? ')    computer_choice = randint(0,2)    #Rock = 0 Paper = 1 Scissors = 2    #Player chooses paper, computer chooses rock    if player_choice == "p" and computer_choice == 0:        print 'Computer chose rock'        player_won()    #Player chooses rock, computer chooses scissors    elif player_choice == 'r' and computer_choice == 2:        print 'Computer chose scissors'        player_won()    #Player chooses scissors, computer chooses paper    elif player_choice == 's' and computer_choice == 1:        print 'Computer chose paper'        player_won()    #Computer chooses paper, player chooses rock    elif player_choice == 'r' and computer_choice == 1:        print 'Computer chose paper'        computer_won()    #Computer chooses rock, player chooses scissors    elif player_choice == 's' and computer_choice == 0:        print 'Computer chose rock'        computer_won()    #Computer chooses scissors, player chooses paper    elif player_choice == 'p' and computer_choice == 2:        print 'Computer chose scissors'        computer_won()    #Ties    elif player_choice == 'r' and computer_choice == 0:        print "It's a tie!"        game()    elif player_choice == 's' and computer_choice == 2:        print "It's a tie!"        game()    elif player_choice == 'p' and computer_choice == 1:        print "It's a tie!"        game()    #Wrong input    else:        print 'Please try again.'        game()def player_won():    global player_count    print 'You win!'    player_count += 1    print 'You have ' + str(player_count) + ' point(s).'    while player_count < 3:        game()def computer_won():    global comp_count    print 'Computer wins!'    comp_count += 1    print 'Computer has ' + str(comp_count) + ' point(s).'    while comp_count < 3:        game()print 'Welcome to Rock, Paper, Scissors! First to 3 points wins it all.'game()

回答：

你的while循环是导致问题的根源。只要在你的player_won和computer_won函数中将while改为if，就可以解决这个问题。

def player_won():    global player_count    print 'You win!'    player_count += 1    print 'You have ' + str(player_count) + ' point(s).'    if player_count < 3:        game()def computer_won():    global comp_count    print 'Computer wins!'    comp_count += 1    print 'Computer has ' + str(comp_count) + ' point(s).'    if comp_count < 3:        game()

现在，尽情享受你的石头剪刀布游戏吧！
