Question

这里的代码总共实现了它的目的，除了我无法让代码结束并打印“你赢了！”毕竟四个数字都已经猜到了。我们尝试过使用break语句，用“whiles”和“elifs”切换“ifs”以及更改变量

import random
#Gets 4 random single digits to be guesses
n1 = random.randint (0,9)
n2 = random.randint (0,9)
n3 = random.randint (0,9)
n4 = random.randint (0,9)

wrong_guesses = 0

print ("I'm thinking of a 4-digit code. Guess what it is!")
print ("X = wrong guess, O = right guess")

guess = int(input("Enter your 4-number digit here:"))

#Guesses the first (leftmost) number
if guess // 1000 % 10 != n1:
    wrong_guesses +=1
    print ('X')
else:
    wrong_guesses +=0   
    print ('O')
#Guesses the second (second from the left) number
if guess // 100 % 10 != n2:
    wrong_guesses +=1
    print ('X')
else:
    wrong_guesses +=0 
    print ('O')
#Guesses the third (second from right) number
if guess // 10 % 10 != n3:
    wrong_guesses +=1
    print ('X')
else:
    wrong_guesses +=0 
    print ('O')

#Guesses the last (rightmost) number
if guess // 1 % 10 != n4:
    wrong_guesses +=1
    print ('X')
else:
    wrong_guesses +=0 
    print ('O')
if wrong_guesses == 0:
    print ("You win!")
while wrong_guesses != 0:
    guess = int(input("Enter your 4-digit code here:"))
   #Display O if number is correct, X if otherwise
if guess // 1000 % 10 != n1:
    wrong_guesses +=1
    print ('X')
else:
    wrong_guesses +=0 
    print ('O')
if guess // 100 % 10 != n2:
    wrong_guesses +=1
    print ('X')
else:
    wrong_guesses +=0 
    print ('O')
if guess // 10 % 10 != n3:
    wrong_guesses +=1
    print ('X')
else:
    wrong_guesses +=0 
    print ('O')
if guess // 1 % 10 != n4:
    wrong_guesses +=1
    print ('X')
else:
    wrong_guesses +=0 
    print ('O')
if guess == n1 and guess == n2 and guess == n3 and guess == n4:
 print ("You win!")

以下是代码无法结束的部分。代码不再显示正确答案的验证，而是继续要求更多数字，如果数字已被猜到则为evem

我认为问题出在你写的时候：

while wrong_guesses != 0:
    guess = int(input("Enter your 4-digit code here:"))

由于您无法在循环中更改wrong_guesses值，因此您将进入无限循环。

我试着通过在这个循环中抛出一些调试打印来验证它，看看是否是这种情况。

另外，不要“尝试使用break语句，切换”ifs“with”whiles“和”elifs“以及更改变量”而不理解你在做什么。

希望这有帮助。

如果用户已经猜到该号码，如何让程序停止询问“4位数”，并使程序显示“你赢了！”
