為什么我的輸入語句不接受程序中的值？

Question

我正在制作一個生成隨機數的程序，並要求您猜測 1-100 范圍之外的數字。 輸入數字后，它會根據該數字生成響應。 在這種情況下，如果輸入為0 ，則為Too high 、 Too low 、 Correct或Quit too soon ，程序結束（簡化，但基本相同）。

它根據您必須輸入 function 的次數來計算嘗試次數，並使用 while 循環不斷詢問數字，直到您輸入正確為止。 （順便說一句，是的，我意識到這部分是我另一個問題的副本。這是同一程序中的不同問題，所以我以同樣的方式開始。）

無論如何，我對程序的最后一部分沒有采取任何價值有疑問。 它應該接受keep_playing的輸入，如果它等於'y'則繼續播放。 問題是它實際上並沒有使變量等於任何東西（至少我不這么認為。）所以，無論我輸入什么值，它每次都會打印相同的響應。 這是代碼的一小部分不起作用，盡管我覺得代碼的 rest 有問題：

def keep_playing(attempts,keep_playing):
    keep_playing = 'y'
    if keep_playing == 'y':
        guess(attempts)
        keep_playing = str(input("Another game (y to continue)? "))
    else:
        print()
        print("Thanks for playing")
    return keep_playing

預期的 output 是：

Enter a number between 1 and 100, or 0 to quit: 4
Too low, try again       It's 66 for testing purposes
Enter a number between 1 and 100, or 0 to quit: 67
Too high, try again      It's 66 for testing purposes
Enter a number between 1 and 100, or 0 to quit: 66

Congratulations! You guessed the right number!
There were 2 attempts

Another game (y to continue)? y

Enter a number between 1 and 100, or 0 to quit: 0

You quit too early
The number was  79
Another game (y to continue)? n

Thanks for playing!

但實際的 output 是：

Enter a number between 1 and 100, or 0 to quit: 4
Too low, try again       It's 66 for testing purposes
Enter a number between 1 and 100, or 0 to quit: 67
Too high, try again      It's 66 for testing purposes
Enter a number between 1 and 100, or 0 to quit: 66

Congratulations! You guessed the right number!
There were 2 attempts

Another game (y to continue)? y

Enter a number between 1 and 100, or 0 to quit: 0

You quit too early
The number was  79
Another game (y to continue)? n
Another game (y to continue)? y
>>>

請注意，無論我做什么，它都會繼續運行。 較高和較低的第一部分工作正常，但底部似乎壞了，我不知道如何修復它。 如果有人有任何解決方案，將不勝感激。

另外，如果有人想看到整個事情，如果有問題的話，這里是：

import random

def main():
    global attempts
    attempts = 0
    guess(attempts)
    keep_playing(attempts,keep_playing)
    
def guess(attempts):
    number = random.randint(1,100)
    print('')
    guess = int(input("Enter a number between 1 and 100, or 0 to quit: "))
    while guess != 0: 
        if guess != number:
            if guess < number:
                print("Too low, try again       It's",number, "for testing purposes") #printing the number makes it easier to fix :/
                attempts += 1
                guess = int(input("Enter a number between 1 and 100, or 0 to quit: "))
            elif guess > number:
                print("Too high, try again      It's",number, "for testing purposes")
                attempts += 1
                guess = int(input("Enter a number between 1 and 100, or 0 to quit: "))
        else:
            print()
            print("Congratulations! You guessed the right number!")
            print("There were", attempts,"attempts")
            print()
            keep_playing = str(input("Another game (y to continue)? "))
            return keep_playing
            
    else:
        print()
        print("You quit too early")
        print("The number was ",number)
        keep_playing = str(input("Another game (y to continue)? "))
        return keep_playing
        
    
    

def keep_playing(attempts,keep_playing):
    keep_playing = 'y'
    if keep_playing == 'y':
        guess(attempts)
        keep_playing = str(input("Another game (y to continue)? "))
    else:
        print()
        print("Thanks for playing")
    return keep_playing
main()
            

Answer 1

我注意到這里有幾件事

1. 您的 function 的命名存在一些問題，python 認為keep_playing是 str 變量keep_playing而不是 function。在我下面的代碼中，我將 function keep_playing重命名為keep_playing_game 。
2. 您需要在調用 function keep_playing_game時傳入參數，以便 function 知道用戶輸入和嘗試的內容。
3. 為什么要在 function def keep_playing_game(attempts,keep_playing)的第一行中設置keep_playing = 'y' ？ 如果刪除此行，您的程序應根據用戶輸入的值而不是 function 分配給keep_playing的值按預期運行。

我建議嘗試這樣的事情

import random

def main():
    global attempts
    attempts = 0
    guess(attempts)
    # keep_playing(attempts,keep_playing) -> this line should be removed
    
def guess(attempts):
    number = random.randint(1,100)
    print('')
    guess = int(input("Enter a number between 1 and 100, or 0 to quit: "))
    while guess != 0: 
        if guess != number:
            if guess < number:
                print("Too low, try again       It's",number, "for testing purposes") #printing the number makes it easier to fix :/
                attempts += 1
                guess = int(input("Enter a number between 1 and 100, or 0 to quit: "))
            elif guess > number:
                print("Too high, try again      It's",number, "for testing purposes")
                attempts += 1
                guess = int(input("Enter a number between 1 and 100, or 0 to quit: "))
        else:
            print()
            print("Congratulations! You guessed the right number!")
            print("There were", attempts,"attempts")
            print()
            keep_playing = str(input("Another game (y to continue)? "))
            return keep_playing_game(keep_playing, attempts)
            
    else:
        print()
        print("You quit too early")
        print("The number was ",number)
        keep_playing = str(input("Another game (y to continue)? "))
        return keep_playing_game(keep_playing, attempts)
        
    
    

def keep_playing_game(keep_playing, attempts):
    if keep_playing == 'y':
        guess(attempts)
    else:
        print()
        print("Thanks for playing")
        return
    return None
main()
