以下代码并未终止，不确定原因。

def main():
    pass

if __name__ == '__main__':
    main()

def GuessingGame (): # creating def function for GuessingGame
    yes = ['y', 'Y', 'Yes', 'yes'] # setting variables

    attempts = 0
    name = input('What is your name? ') # asks user for name and introduces the game
    print('Nice to meet you', name, '! I am going to pick a random number and you will have 3 tries to guess it.'
    'Good luck!')

while attempts < 3: # creates a function
    guess = int(input('Guess the number I have chosen between 1 and 10. '))
    attempts += 1
    if guess == numbertoguess: # tells user if guess is right
        print('Great guess, youre right', name, '!')

def main():
    pass

if __name__ == '__main__':
    main()
import random # imports random
# Your 2 while loops were not indented causing them not to know what the attempt variable, made in the GuessingGame function was.
def GuessingGame (): # creating def function for GuessingGame
    yes = ['y', 'Y', 'Yes', 'yes'] # setting variables
    rng = random.Random ()
    numbertoguess = rng.randrange (1,10)  # setting random number between 1 and 10
    correctguesses = 0
    winpercent = 0
    attempts = 0
    name =  raw_input('What is your name? ') # asks user for name and introduces the game (inputs used in strings must be raw.) 
    print('Nice to meet you', name ,'! I am going to pick a random number and you will have 3 tries to guess it.'
'Good luck!')

    while attempts < 3: # creates a function
        guess = int(input('Guess the number I have chosen between 1 and 10. '))
        attempts += 1
        if guess == numbertoguess: # tells user if guess is right
            print('Great guess, youre right', name, '!')
            correctguesses += 1 # adds on to correct guesses
            winpercent = float((correctguesses*100)/attempts)# determines percent of correct answers
            print ('You have' , correctguesses, 'correct guesses!')
            print ('You are right', winpercent, 'of the time.')
        elif guess > numbertoguess: # tells if guess is too high
            print('The number is lower than', guess, "!")
        elif guess < numbertoguess: # tells if guess is too low
            print('The number is higher than', guess, "!")
        else: # tells when you have lost
            print('Wrong, the number was', numbertoguess, '!')
            print ('You have' , correctguesses, 'correct guesses!')
            print ('You are right', winpercent, 'of the time.')
    gameover = raw_input("Do you want to play again? Yes or No? ")

while gameover is 'Yes' or 'yes': GuessingGame () #oportunity to  play again
    else: exit() # ends games
    print ('The program will now terminate. Goodbye.')
GuessingGame () # calls game`enter code here`

有两个原因导致您的代码无效。第一个是while循环不在GuessingGame函数内部，导致他们不知道变量是由什么产生的。第二个原因是，如果要在字符串中使用输入，则必须使用raw_input（），而不是普通输入（）。我希望这有帮助！

Answer 2

我相信你的问题在行while gameover is 'Yes' or 'yes': GuessingGame ()如果用户输入yes是否想要再次玩游戏，你会反复调用该函数，这称为递归。如果我是正确的，这会将尝试重置为0，因此永远不会退出while循环。我不确定这是否是你想要的，但不是调用GuessingGame（），而是写while gameover is 'Yes' or 'yes': continue实际上会回到while循环的顶部。

另外，我不太确定定义main（）函数的重要性是什么，当函数的主体刚刚通过时。相反，如果名称 =='主要'，您应该在上面写上您的GuessinGame（），如果名称，则在下面设置while循环 ==' main '
