无法让 while 循环按照我的意图工作

Question

我正在做一个练习来创建一个石头剪刀布游戏。

我试图通过设置玩家可以玩游戏的次数来超出练习的要求。玩家可以在游戏开始时选择他们想要玩的手数。

问题是，到目前为止，我从未将 While 循环与函数结合使用，而且我遇到了问题，我希望有人能帮助我解决这个问题并告诉我哪里错了。

另外，我觉得我的代码太长了，关于如何最小化它的任何建议？

更新 1 我通过将 while 循环从函数之前移动并将其应用于最后一部分来使其工作，如下所示： 但是现在我试图在最后打印一条带有玩家分数的消息，但是，Python 无法识别 player_1_scroe 变量 beachs 在函数内部。你将如何解决这个问题？

player_1 = input("Enter player 1 Name: ").capitalize()
player_2 = input("Enter player 2 Name: ").capitalize()
game_limit = int(input("Enter how many hands you want to play"))
play_count = 0


def play(usr1, usr2):
    player_1_points = 0
    player_2_points = 0

    if usr1 == usr2:
        player_1_points += 1
        player_2_points += 1
        return "Its a Tie!"

    elif usr1 == "r":
        if usr2 == "p":
            player_2_points += 1
        return f"{player_2} wins!"

    elif usr1 == "r":
        if usr2 == "s":
            player_1_points += 1
        return f"{player_1} wins!"

    elif usr1 == "p":
        if usr2 == "r":
            player_1_points += 1
        return f"{player_1} wins!"

    elif usr1 == "p":
        if usr2 == "s":
            player_2_points += 1
        return f"{player_2} wins!"

    elif usr1 == "s":
        if usr2 == "p":
            player_1_points += 1
        return f"{player_1} wins!"

    elif usr1 == "s":
        if usr2 == "r":
            player_2_points += 1
            return f"{player_2} wins!"


print("Enter hand:\n(R)ock\n(P)aper\n(S)cissors")

while True:
    if play_count < game_limit:
        game_play1 = input(f"{player_1}, enter your hand: ").lower()
        game_play2 = input(f"{player_2}, enter your hand: ").lower()

        print(play(game_play1, game_play2))
        play_count += 1
    elif player_1_points > player_2_points:
        print(f"{player_1} is the winer with {player_1_points} points!"
        print("Game Over")
        break
    else:
        print(f"{player_2} is the winer with {player_2_points} points!"
        print("Game Over")
        break

在函数外部声明你的变量 player_1_points 和 player_2_points。

使用关键字'global'来改变函数内部的变量。

player_1 = input("Enter player 1 Name: ").capitalize()
player_2 = input("Enter player 2 Name: ").capitalize()
game_limit = int(input("Enter how many hands you want to play"))
play_count = 0
player_1_points = 0
player_2_points = 0

def play(usr1, usr2):
    global player_1_points
    global player_2_points
    if usr1 == usr2:
        player_1_points += 1
        player_2_points += 1
        return "Its a Tie!"

    elif usr1 == "r":
        if usr2 == "p":
            player_2_points += 1
        return f"{player_2} wins!"

    elif usr1 == "r":
        if usr2 == "s":
            player_1_points += 1
        return f"{player_1} wins!"

    elif usr1 == "p":
        if usr2 == "r":
            player_1_points += 1
        return f"{player_1} wins!"

    elif usr1 == "p":
        if usr2 == "s":
            player_2_points += 1
        return f"{player_2} wins!"

    elif usr1 == "s":
        if usr2 == "p":
            player_1_points += 1
        return f"{player_1} wins!"

    elif usr1 == "s":
        if usr2 == "r":
            player_2_points += 1
            return f"{player_2} wins!"



print("Enter hand:\n(R)ock\n(P)aper\n(S)cissors")
while True:
    if play_count < game_limit:


        game_play1 = input(f"{player_1}, enter your hand: ").lower()
        game_play2 = input(f"{player_2}, enter your hand: ").lower()

        print(play(game_play1, game_play2))
        play_count += 1
    elif player_1_points > player_2_points:
        print(f"{player_1} is the winer with {player_1_points} points!")
        print("Game Over")
        break
    else:
        print(f"{player_2} is the winer with {player_2_points} points!")
        print("Game Over")
        break
