Python-如何在呼叫另一個函式后回傳上一個函式？

這是我的代碼副本 :) 這個游戲是我個人活動的一部分。所以在購買了一條線索（來自：def game_hints）后，我想回到def Game_process。

import random     
    SCORE = 0
    ROUNDS = 1
          
    def player_stats():
        print(f"SCORE: {SCORE} | ROUNDS: {ROUNDS}")
    
    def game_hints(USER_GUESS, Mystery_NUM):
        print("Would you like purchase a hint for 5 points? [1/2]: ")
        USER_HINT = int(input())
        global SCORE
        if USER_HINT == 1:
         SCORE= SCORE - 5
         if USER_GUESS > Mystery_NUM and Mystery_NUM % 2 == 0:
          print("Mystery Num is even and try a smaller guess")
         elif USER_GUESS > Mystery_NUM and Mystery_NUM % 2 == 1:
          print("Mystery Num is odd and try a smaller guess")
         elif USER_GUESS < Mystery_NUM and Mystery_NUM % 2 == 0: 
          print("Secret Num is even and try a larger guess")
         elif USER_GUESS < Mystery_NUM and Mystery_NUM % 2 == 1:
          print("Mystery Num is odd and try a larger guess") 
 
      
    def Game_Process():
     global ROUNDS
    
     while True:
      if ROUNDS <= 10:   
        Mystery_NUM = random.randrange(10)
        print(Mystery_NUM) #remove before final product 
        print("Guess the num [1-10]: ")
        USER_GUESS = int(input())
        if USER_GUESS == Mystery_NUM:
            print("\nGood Job!  5 Coins!")
            global SCORE
            SCORE = SCORE   10
            ROUNDS  = 1
            player_stats()    
        else:
            print("Wrong! Try Again")
            game_hints(USER_GUESS, Mystery_NUM)
      else:
        print("Game Over!")
        Game()        
    
    def Game():
        user_opt = input("\"Welcome to Guess Game\" \nPress [Y] to Play or [N] to Exit: ").lower()
        if user_opt == "n":
            print("Good bye!")
            exit()
        elif user_opt == "y":
            Game_Process()
        else:
            print("Invalid Input! [1/2]")
            Game()
    Game()

如下圖，這是提示的作用。我能夠呼叫這個函式，但唯一的問題是這個函式完成后，它改變了 Myster_Num。

def game_hints(USER_GUESS, Mystery_NUM):
    print("Would you like purchase a hint for 5 points? [1/2]: ")
    USER_HINT = int(input())
    global SCORE
    if USER_HINT == 1:
     SCORE= SCORE - 5
     if USER_GUESS > Mystery_NUM and Mystery_NUM % 2 == 0:
      print("Secret Num is even and try a smaller guess")
     elif USER_GUESS > Mystery_NUM and Mystery_NUM % 2 == 1:
      print("Secret Num is odd and try a smaller guess")
     elif USER_GUESS < Mystery_NUM and Mystery_NUM % 2 == 0: 
      print("Secret Num is even and try a larger guess")
     elif USER_GUESS < Mystery_NUM and Mystery_NUM % 2 == 1:
      print("Mystery Num is odd and try a larger guess") 

uj5u.com熱心網友回復：

首先，您必須洗掉game_hints函式中的 else 陳述句，因為它會重新啟動完整的GameProcess，因此確實會重新計算一個神秘數字。

然后，當您退出game_hints并回傳GameProcess 時，您一定不要回到大回圈，因為它確實會重新計算一個神秘的數字。解決方案是在每一輪內有一個內部回圈，只有當玩家使用break關鍵字猜出正確的值時才退出。

def Game_Process():
    SCORE = 0
    ROUNDS = 1
    while True:
        if ROUNDS <= 10:
            Mystery_NUM = random.randrange(10)
            print(Mystery_NUM)  # remove before final product
            while True:
                print("Guess the num [1-10]: ")
                USER_GUESS = int(input())
                if USER_GUESS == Mystery_NUM:
                    print("\nGood Job!  5 Coins!")
                    SCORE = SCORE   10
                    ROUNDS  = 1
                    player_stats()
                    break
                else:
                    print("Wrong! Try Again")
                    game_hints(USER_GUESS, Mystery_NUM)
        else:
            print("Game Over!")
            Game()
