python - NameError:在封闭范围内赋值之前引用了自由变量 'player_one_rps'

Question

我对编码很陌生，我一直在尝试制作一个带有菜单的基于文本的游戏。游戏本身工作正常，但一旦我尝试合并菜单，我收到错误“NameError:在封闭范围内分配之前引用了自由变量'player_one_rps'”。我已经疯狂地用谷歌搜索它有一段时间了，但我找到的几个答案使用了太高级的代码，我还无法理解它。

(我尝试更改范围和缩进，我尝试在不同的缩进处调用不同的函数，我尝试为函数分配一个参数，还尝试将主菜单作为代码中的最后一个函数 - 列表还在继续。 .)

这是菜单和游戏选项 1 的代码:

定义主函数(): print("\t\t*** 欢迎来到这个完全足够的游戏!***")

def game_menu():
    """Displays game menu and prompts user for input"""
    menu_choice = input("""What do you want to do?

                        1 - One player: rock, paper, scissor, lizard, spock
                        2 - Two player: rock, paper, scissor, lizard, spock
                        3 - Surprise! Bonus feature
                        4 - User guide
                        5 - Quit

                        Enter the menu number to access: """)
    while True:
        if menu_choice == "1":
            print("One player: rock, paper, scissor, lizard, spock")
            player_one_rps()
            break
        elif menu_choice == "2":
            print("Two player: rock, paper, scissor, lizard, spock")
            player_two_rps()

            exit()
        elif menu_choice != 1 - 5:

(抱歉，如果它很长)

有人可以帮我指出我的错误方向吗？有关如何修复它的解释和提示也将不胜感激:)

总的来说，我很感谢所有的反馈，因为我真的想在编码方面变得更好。

全局函数必须具有比调用它的地方更高的声明代码。只需重新定位该功能即可。函数 game_menu 必须位于函数 play_one_rps 下面。其他功能相同。
