Question

我正在学习python（版本3），并且您可能已经知道，练习之一是创建一个石头剪刀布蜥蜴spock（rpsls）游戏，我被要求从下面的if语句开始，然后修改代码以包含循环并使用随机函数添加计算机播放器。我花了几天时间调整代码并进行谷歌搜索，但是我无法解决循环中断问题。它卡住了，不断要求玩家1输入，并且永远不会加载与玩家2的比较或完成回合。我意识到这是一种编写游戏代码的麻烦方式，但我想尽可能保留格式。

        import random

print("")
print("**** Welcome to Rock Paper Scissors ****")
print("")



inputOK = False
player2choices = ['rock', 'paper', 'scissors', 'lizard', 'spock']
while inputOK == False:
    stringPlayer1 = input("Player 1, choose: rock, paper, scissors, lizard, or spock: ")

    stringPlayer2 = random.choice(player2choices)
if stringPlayer1 == stringPlayer2:
    print("Tie: Both players chose:" +
          stringPlayer1)

elif stringPlayer1 == 'scissors' and stringPlayer2 == 'paper':
    print("Player 1 wins: scissors cuts paper.")

elif stringPlayer1 == 'paper' and stringPlayer2 == 'rock':
    print("Player 1 wins: paper covers rock.")

elif stringPlayer1 == 'rock' and stringPlayer2 == 'lizard':
    print("Player 1 wins: rock crushes lizard.")

elif stringPlayer1 == 'lizard' and stringPlayer2 == 'spock':
    print("Player 1 wins: lizard poisons spock.")

elif stringPlayer1 == 'spock' and stringPlayer2 == 'scissors':
    print("Player 1 wins: Spock smashes scissors.")

elif stringPlayer1 == 'scissors' and stringPlayer2 == 'lizard':
    print("Player 1 wins: scissors decapitates lizard.")

elif stringPlayer1 == 'lizard' and stringPlayer2 == 'paper':
    print("Player 1 wins: lizard eats paper.")

elif stringPlayer1 == 'paper' and stringPlayer2 == 'spock':
    print("Player 1 wins: paper disproves Spock.")

elif stringPlayer1 == 'spock' and stringPlayer2 == 'rock':
    print("Player 1 wins: Spock vaporizes rock.")

elif stringPlayer1 == 'rock' and stringPlayer2 == 'scissors':
    print("Player 1 wins: rock crushes scissors.")

elif stringPlayer1 == 'paper' and stringPlayer2 == 'scissors':
    print("Player 2 wins: scissors cuts paper.")

elif stringPlayer1 == 'rock' and stringPlayer2 == 'paper':
    print("Player 2 wins: paper covers rock.")

elif stringPlayer1 == 'lizard' and stringPlayer2 == 'rock':
    print("Player 2 wins: rock crushes lizard.")

elif stringPlayer1 == 'spock' and stringPlayer2 == 'lizard':
    print("Player 2 wins: lizard poisons spock.")

elif stringPlayer1 == 'scissors' and stringPlayer2 == 'spock':
    print("Player 2 wins: Spock smashes scissors.")

elif stringPlayer1 == 'lizard' and stringPlayer2 == 'scissors':
    print("Player 2 wins: scissors decapitates lizard.")

elif stringPlayer1 == 'paper' and stringPlayer2 == 'lizard':
    print("Player 2 wins: lizard eats paper.")

elif stringPlayer1 == 'spock' and stringPlayer2 == 'paper':
    print("Player 2 wins: paper disproves Spock.")

elif stringPlayer1 == 'rock' and stringPlayer2 == 'spock':
    print("Player 2 wins: Spock vaporizes rock.")

elif stringPlayer1 == 'scissors' and stringPlayer2 == 'rock':
    print("Player 2 wins: rock crushes scissors.")

else:
    inputOK = False
    print("Error: Not a valid choice.")

quit = input("Do you want to quit? ")
if quit.lower() == "y" or quit.lower() == "yes":
    done = True

Answer 1

while循环将继续循环直到您的变量inputOk等于True。您的错误是，当玩家想要结束游戏时，inputOK没有更新为True。也许您打算将inputOk设置为True而不是完成？

quit = input("Do you want to quit? ") if quit.lower() == "y" or quit.lower() == "yes": inputOk = True

编辑：同样如前所述，您必须缩进python。在while语句下未缩进的任何代码都不会循环。

Answer 2

用户将陷入无限循环，除非在while循环中的某个地方内通过设置inputOK = True来更改条件。

在此之前，您需要确定有效输入的条件，例如用户输入是有效选择之一（if stringPlayer1 in player1choices）

player2choices = ['rock', 'paper', 'scissors', 'lizard', 'spock']
player1choices = player2choices

while inputOK == False:
    stringPlayer1 = input("Player 1, choose: rock, paper, scissors, lizard, or spock: ")
    if stringPlayer1 in player1choices: # a condition for valid input?
        inputOK = True
    stringPlayer2 = random.choice(player2choices)

那至少应该解决这个破环，并使您可以继续开发游戏。
