while 循环无法中断

Question

有NameError: name 'user' is not defined

为什么while循环没有结束请帮助找到问题

该程序用于 pyhton 中的掷骰子我想毫无例外地掷骰子，但有异常发生

rand_num=random.randint(1, 6)
game_is_on=True    
while True:
    try:
        user=int(input("What's your choice : "))
        continue
    except:
        print("Please Enter 1-6")

    if user == rand_num:
        print("\t congrats ! \n You guessed it right 🎊")
    elif user != rand_num:
        print("Sorry! your guess is incorrect🥺")
        
    replay=input("Do you want to play again (Yes/No)")
    if replay =='yes'.lower():
        game_is_on=True
    else:
        print("Thanks for playing this game")
        game_is_on=False```


hlep to find the problem please

Answer 1

要退出循环：

• 您的 while 循环将永远为真，但您切换了一个用于调节循环的变量game_is_on 。 而不是永远循环， game_is_on应该在 while 旁边，
• 您需要删除continue语句，因为只要条件为真，该行将只是 go 到下一次迭代，
• 当被问及重放时，较低的部分应该在变量上，而不是降低字符串本身。

以下是您需要的代码：

rand_num=random.randint(1, 6)
game_is_on=True
# while True:    
while game_is_on:
    try:
        user=int(input("What's your choice : "))
        # continue
    except:
        print("Please Enter 1-6")

    if user == rand_num:
        print("\t congrats ! \n You guessed it right 🎊")
    elif user != rand_num:
        print("Sorry! your guess is incorrect🥺")
        
    replay=input("Do you want to play again (Yes/No)")
    if replay.lower() =='yes':
        game_is_on=True
    else:
        print("Thanks for playing this game")
        game_is_on=False

快乐编码！

Answer 2

导入随机 rand_num=random.randint(1, 6) game_is_on=True
while game_is_on: try: user=int(input("What's your choice: ")) except: print("Please Enter 1-6")

if user == rand_num:
    print("\t congrats ! \n You guessed it right 🎊")
elif user != rand_num:
    print("Sorry! your guess is incorrect🥺")
    
replay=input("Do you want to play again (Yes/No)")
if replay =='yes'.lower():
    game_is_on=True
else:
    print("Thanks for playing this game")
    game_is_on=False

注意：在while循环中，您必须为该变量编写'game_is_on'，它会告诉您是真还是假，而不是您写了True，因此您的循环将永远不会结束，因为没有任何东西破坏循环更正的代码粘贴在上面，希望这可能会有所帮助你。

您可以使用运算符 break 来结束 while 循环。 lower() 应该与变量一起使用。

   if replay.lower() != 'yes':
    print("Thanks for playing this game")
    break
