Python - 如何將定義的變量從一個 function 獲取到另一個 function？

Question

我已將其簡化為：

def hang():
p = 1
while p == 1:
    gameinput = input("Please select a gamemode, Type [1] for one player or Type [2] for two player: ")
    if gameinput == "2":
     def two_player_word():
         print("2")
    elif gameinput == "1":
     def one_player_word():
         print("1")


def hangman():
    if gameinput == "2":
        word = two_player_word()
    elif gameinput == "1":
        word = one_player_word()
    print("Word")

def main():
    gamerestart = 1
    while gamerestart == 1:
        print()
        print("Would you like to play again?")
        gameoverinput = input("Press [1] to play again, Press [2] to exit program. ")
        if gameoverinput == "1":
            for i in range(0, 25):
                print()
            hangman()
        elif gameoverinput == "2":
            print("Thank you for playing, goodbye....")
            time.sleep(2)
            quit()
        else:
            print("Invaild option.")

if  __name__ == "__main__":
    main()

我之前在 'hang()' 中定義了游戲輸入，它收集用戶輸入等等。 我的問題在'hangman（）'中我需要再次游戲輸入來制作變量詞（它是這樣制作的，因此用戶可以在生成隨機詞時制作一個詞（two_player_word）或一個玩家（one_player_word（）

如果沒有游戲輸入在 function 中，它可以完美運行，但是在玩家贏或輸之后，我希望它讓用戶決定是否要更改游戲模式，如 main() 所示。

還有更多代碼，但認為僅使用它來嘗試找出問題會更容易。

Answer 1

只需將游戲輸入從hang hangman gameinput參數。

def hang():
    while True:
        gameinput = input("Please select a gamemode, Type [1] for one player or Type [2] for two player: ")
        if gameinput not in ("1", "2"):
            continue
        hangman(gameinput)
        break


def hangman(gameinput):
    if gameinput == "2":
        word = two_player_word()
    elif gameinput == "1":
        word = one_player_word()
    print("Word")

Answer 2

有兩個問題會導致您的代碼失敗（縮進除外）。

1. 您正在定義嵌套函數（ one/two_player_word ），然后嘗試從 function （未定義）外部調用。 您可以通過在 function hang()之外定義函數來更改此設置。
2. hangman()使用 gameinput 變量，但它沒有定義也沒有提供。 您可以通過將其作為參數添加到 function 調用來更改此設置。

您調整后的代碼可以像這樣工作：

import time

def one_player_word():
  print("1")

def two_player_word():
  print("2")

def hang():
  p = 1
  while p == 1:
      gameinput = input("Please select a gamemode, Type [1] for one player or Type [2] for two player: ")
      if gameinput == "2":
        two_player_word()
      elif gameinput == "1":
        one_player_word()

def hangman(gameinput):
    if gameinput == "2":
        word = two_player_word()
    elif gameinput == "1":
        word = one_player_word()
    print("Word")

def main():
    gamerestart = 1
    while gamerestart == 1:
        print()
        print("Would you like to play again?")
        gameoverinput = input("Press [1] to play again, Press [2] to exit program. ")
        if gameoverinput == "1":
            for i in range(0, 25):
                print()
            hangman(gameoverinput)
        elif gameoverinput == "2":
            print("Thank you for playing, goodbye....")
            time.sleep(2)
            quit()
        else:
            print("Invaild option.")

if  __name__ == "__main__":
    main()
