Question

我对编程完全陌生。我开始使用最简单的newbs语言，python。我创建了这个简单的猜数字游戏。但我的问题是，当你猜测脚本没有结束的数字时，它就会不断重复。我想知道为什么。谢谢。

P.S。任何其他提示将非常感激，如如何改进编码。请记住，我是一个全新的人，我并不是很了解很多功能，所以要尽可能简单和居高临下（我不介意）。干杯啦！ [嗯......我怎么让这个更加变质？我想编辑脚本间距有点不断，因为它需要更加宽泛，所以希望这个额外的文本会让它变得更加分散...只是忽略这部分]

import random
running = True

while running:
    guessTaken = 0
    print("Hello! What is your name? ")
    myName = input()

    number = random.randint(0,10)
    print("Well, " +myName+ ", I am thinking of a number between 1 and 10.")
    print("I'll give you 10 guesses, see if you can guess the number I'm thinking of!")

    while guessTaken < 10:
        guess = input("Go on! Take a guess: ")
        guess = int(guess)

        guessTaken += 1

        if number > guess:
            print("Too low!")
        if number < guess:
            print("Too high!")
        if number == guess:
            print("You got it!")
            guessTakenstr = str(guessTaken)
            print("Good job " +myName+ ", you guessed my number in " +guessTakenstr+ " guesses!")
            input("Press <enter> to exit")
            running = False

    if number != guess:
        number = str(number)
        print("Sorry, you've had your 10 goes! The number I was think of was " +number)
        running = False

Answer 1

您需要更改条件

while guessTaken < 10:

到

while (guessTaken < 10) and running:

修改

添加更多解释。 while循环将检查条件guessTaken < 10并继续运行10次，无论您的输入是什么（因为guessTaken在循环中递增一次）。为了摆脱循环，您需要在此处添加break语句

if number == guess: print("You got it!") guessTakenstr = str(guessTaken) print("Good job " +myName+ ", you guessed my number in "+guessTakenstr+ " guesses!") input("Press <enter> to exit") running = False break # Break statement added

或者如果用户在我的回答中给出了正确的输入，则需要在进入循环之前（再次）进行检查

while (guessTaken < 10) and running:

Answer 2

我猜测你的内部while循环的缩进在你的程序中实际上是正确的（也就是它在while running:循环中缩进了2个空格） -

  print("I'll give you 10 guesses, see if you can guess the number I'm thinking of!")

  while guessTaken < 10:

否则该程序甚至不会到达猜测数字的部分。

在这种情况下，问题在于你的if部分当数字等于猜测时，即使你正在设置running=False，你也不会突破内部的while循环，所以你的程序仍会继续直到你进行10次猜测。

此外，从程序看起来你真的不需要外循环，因为经过10次猜测你仍然退出循环（所以它只运行一次迭代），如果是这样，你可以删除它完全循环（while running:循环）并跳出while guessTaken < 10:循环。示例 -

guessTaken = 0
print("Hello! What is your name? ")
.
.

while guessTaken < 10:
    .
    .
    if number == guess:
        print("You got it!")
        guessTakenstr = str(guessTaken)
        print("Good job " +myName+ ", you guessed my number in " +guessTakenstr+ " guesses!")
        input("Press <enter> to exit")
        break

if number != guess:
    number = str(number)
    print("Sorry, you've had your 10 goes! The number I was think of was " +number)

当你猜到这个号码时，为什么我的简单猜谜游戏会结束呢？
