python - 数字游戏 : Can't Win: Won't print: You Win, 但结束脚本

Question

我的问题是，当我得到正确的数字时，python 脚本结束，但不打印:你赢了!

import random 

number = random.randint(1,100) # This part works fine

guess = input('Guess a number between 1 and 100: ') #Asks question
guess = float(guess)

tries = 10 

while guess != number and tries > 0 :

    if guess < number:    # This part works fine
        print('Too low')
        tries = tries - 1
        print('You have %s tries left' % (tries))

    if guess > number:
        print('Too high')     # This part is also good
        tries = tries - 1
        print('You have %s tries left' % (tries))

    if tries == 0:
        print('You lose!')
        print('The answer was ' + str(number)) 
        continue

    if guess == number :
        print('You win!')   # Why doesn't this work?
        #Python ends at this line if I get it right, but doesn't print: You win!

    else :
       guess = input('Try Again: ')
       guess = float(guess)

pass     # WHILE*

我只有 11 岁，几个月前才开始编程，请帮助我!

如果猜测正确，您的代码将无法满足第一个条件:

while guess != number and tries > 0 :

如果猜测完成，循环将在 else 语句后中断，并且永远不会返回到 if 条件检查猜测。

由于在输入正确答案之前您无法继续循环，因此您始终可以按如下方式编写:

import random 

number = random.randint(1,100) # This part works fine

guess = input('Guess a number between 1 and 100: ') #Asks question

guess = float(guess)

tries = 10 

while guess != number and tries > 0 :

    if guess < number:    # This part works fine
        print('Too low')
        tries = tries - 1
        print('You have %s tries left' % (tries))

    if guess > number:
        print('Too high')     # This part is also good
        tries = tries - 1
        print('You have %s tries left' % (tries))

    if tries == 0:
        print('You lose!')
        print('The answer was ' + str(number)) 
        continue

    else :
       guess = input('Try Again: ')
       guess = float(guess)

print('You win!')

请记住，其中存在一个错误，该错误会导致用户猜完后，您的获胜结果也会被打印出来。我决定将其留在这里，因为我认为它很容易修复，并且有利于您下定决心从中学习。如果您希望我为您做这件事，请随时在评论中写下。

我还建议在您的帖子中使用代码注释。在这种情况下，我会为您的问题提供如下代码:

import random 

number = random.randint(1,100) # This part works fine

guess = input('Guess a number between 1 and 100: ') #Asks question

guess = float(guess)

tries = 10 

while guess != number and tries > 0 :

    if guess < number:    # This part works fine
        print('Too low')
        tries = tries - 1
        print('You have %s tries left' % (tries))

    if guess > number:
        print('Too high')     # This part is also good
        tries = tries - 1
        print('You have %s tries left' % (tries))

    if tries == 0:
        print('You lose!')
        print('The answer was ' + str(number)) 
        continue

    if guess == number :
        print('You win!')       # Why doesn't this work?
                # Python ends at this line if I get it right, but doesn't print: You win!

    else :
       guess = input('Try Again: ')
       guess = float(guess)

pass     # WHILE*
