蟒蛇3；石头剪刀布 - 只选择一个结果

Question

编写一个小型 RPS 游戏时遇到了问题。

1) 当我运行该函数玩游戏时，它总是以“平局”的形式返回 即使我选择了一个失败的变量 ex。 cpu = 石头，玩家 = 剪刀

我对此感到有些困惑。当我遇到麻烦时，我通常会潜伏在 stackoverflow 论坛上，但我还没有遇到遇到同样问题的人（即使这里有过多的 RPS 问题）。

现在，我不是要求任何人为我编写和测试它 100%，而只是告诉我错误点，我会去解决问题。

谢谢！

def showRules():
    print("********** Rock, Paper, Scissors **********")
    print("Rules: Each player chooses either Rock, Paper, or Scissors.")
    print("       The winner is determined by the following rules:")
    print("       Scissors cuts Paper -> Scissors wins")
    print("       Paper covers Rock   -> Paper Wins")
    print("       Rock smashes Scissors -> Rock Wins")
    print("*******************************************")

def getCPUChoice():
    choices = ["rock", "paper", "scissors"]
    from random import randint
    randNum = randint(0,2)
    cpuchoice = choices[randNum]
    print(cpuchoice)
    return

def getUserChoice():
    choices = ["rock", "paper", "scissors"]
    userchoice = input('Please choose either rock, paper or scissors:').lower()
    print(userchoice)
    return

def declareWinner(user, computer):
    if user == computer:
        print("Tie!!")
    elif user == "rock" and computer == "paper":
        print("You lose!")
    elif user == "paper" and computer == "scissors":
        print("You lose!")
    elif user == "scissors" and computer == "rock":
        print("You lose!")


def playGame():
    showRules()
    computer = getCPUChoice()
    user = getUserChoice()
    declareWinner(user, computer)

Answer 1

在 getCPUChoice 和 getUserChoice 中，您打印的是选择而不是返回它们。将这些函数末尾的返回更改为

    return cpuchoice

和

    return userchoice

分别。
