Question

我是Python的新手，我制作了一个随机数字猜谜游戏。我遇到的问题是，当我达到0个生命时，我无法让程序退出while循环，而是告诉我我有-1个生命或-2个生命，等等。我查看了一下代码，但是我很挣扎看看我的逻辑/编程中的缺陷。任何帮助，将不胜感激！

from random import randint


randomnumber = randint(1, 30)

print("Welcome to the number guessing game!")

game = False
lives = 3

while not game or lives == 0:

    playerguess = int(input("Please enter a number between 1 and 30: "))

    if playerguess > 30 or playerguess < 1:
        print("Please only enter numbers between 1 and 30")
    elif playerguess == randomnumber:
        print("Correct!")
        game = True
    elif playerguess == randomnumber - 1 or playerguess == randomnumber + 1:
        lives -= 1
        print("You were so close! You now have", lives, "lives remaining!")
    else:
        lives -= 1
        print("Not even close! You now have", lives, "lives remaining!")

if game:
    print("Congratulations you won with ", lives, "lives remaining!")
else:
    print("Sorry you ran out of lives!")

Answer 1

更改为此while not game and lives > 0。

您当前的语句while not game or lives == 0，意味着如果生命不为0 或 not game，则循环可以继续，因为您可以用尽生命而无需更改game到True的循环将不会退出。

只有在您的生命超过0且not game可以解决问题后，此新条件才允许运行游戏。

Congratulations you won with  3 lives remaining!
...
Not even close! You now have 0 lives remaining!

对不起，您没钱了！

Answer 2

您的条件不正确：

while not game and lives > 0:

您想在游戏未完成（not game）且生命数大于0（lives > 0）时循环播放。

Answer 3

您应该将while条件提高到while not game and lives > 0或在while循环中添加一个break命令，直到到达lives < 1时才会调用：

...
while not game:

    playerguess = int(input("Please enter a number between 1 and 30: "))

    if playerguess > 30 or playerguess < 1:
        print("Please only enter numbers between 1 and 30")
    elif playerguess == randomnumber:
        print("Correct!")
        game = True
    elif playerguess == randomnumber - 1 or playerguess == randomnumber + 1:
        lives -= 1
        print("You were so close! You now have", lives, "lives remaining!")
    else:
        lives -= 1
        print("Not even close! You now have", lives, "lives remaining!")

    #get out of loop if player died
    if lives < 1:
        break

if game:
...

尝试使用python退出while循环
