main()

因此，当我尝试此代码时，大多数情况下一切正常。我似乎唯一无法工作的是实际的计数部分。当我在玩了多次（甚至一次）后尝试打印我的结果时，代码仍然以零作为游戏总数。有人可以告诉我我在哪里搞砸了，希望能帮我解决这个问题吗？

您的代码中有几个错误。第一个是

winner(gameWinner, printCpu, printPlayer)

将 a 传递function给函数winner。您应该捕获的返回值gameWinner并将其传递给winner

result = gameWinner(printCpu, printPlayer)
winner(result, printCpu, printPlayer)

下一期

def winner(gameWinner, printCpu, printPlayer):     
    if winner == "win":

您忽略了输入参数并将其function自身与字符串“win”进行比较。它将永远是False。这样做的结果是你的win, lose,tie变量永远不会被触及。

最后一个问题是win，lose并且tie是全球性的。所有有经验的程序员都不赞成使用全局变量，但如果你必须使用它们，你应该首先在全局范围内声明变量，而不是在函数 main 内。然后，您应该global在任何引用它们的函数中使用关键字。所以在里面winner我们需要

global win, lose, tie

最小更正的代码看起来像

import random

win=0
lose=0
tie=0 

def main():
    playagain = 1     
    while playagain==1:
        printCpu=cpuConverter()
        printPlayer=playerConverter()
        print("The computers choice is", printCpu)
        print("Your choice is", printPlayer)
        result = gameWinner(printCpu, printPlayer)
        winner(result, printCpu, printPlayer)
        playagain=int(input("Would you like to play again? Enter 1 for yes, any other number for no!"))

    print("Your total wins are", win)
    print("Your total losses are", lose)
    print("Your total ties are", tie)



def cpuConverter():
    cpuChoice=random.randrange(1,4)
    if cpuChoice==1:
        printCpu="Rock"
    elif cpuChoice==2:
        printCpu="Paper"
    else:

    return printCpu

def playerConverter():

        if printPlayer<1 or printPlayer>3:
            print("Invalid choice for the game. Please choose another number inside the constraints.")
        elif printPlayer==1:

            again=1
    return printPlayer

def gameWinner(printCpu, printPlayer):
    if printCpu == printPlayer:
        winner = "tie"
