如何关闭我的＆＃39; while＆＃39;循环所以程序没有无限循环？

def letter_guess(guess):

     if guess in word:
        return True
     else:
        return False

def correct_letter(guess):
    guess = guess
    if letter_guess(guess) == True:
        print ('Correct: ' + guess)
    else:
        wrong_letter(guess)

def wrong_letter(guess):
    guess = guess
    if letter_guess(guess) == False:
        print('Wrong: ' + guess)
    else:
        correct_letter(guess)

#Program starts here
word = 'samsung'
guess = raw_input('Guess a letter: ')
while guess !='':

    letter_guess(guess)

    correct_letter(guess)

    wrong_letter(guess)

程序应该接收原始输入并确定输入是否在对象中。＆＃39;然后它应该继续提出相同的问题，而不是无限循环。

Answer 1

您需要在循环内移动输入。当您了解它时，您可能还希望简化逻辑的其余部分：

while True:
    guess = raw_input('Guess a letter or press Enter to stop: ')
    if guess == '':
        break
    if guess in word:
        print('Correct')
    else:
        print('Incorrect')

Answer 2

在无限循环内询问raw_input，如果不满足条件则中断

while True:
    # your algorithm
    # ...
    if not satisfied:
        break

Answer 3

为什么不在全局设置一个由正确猜测修改的标志变量？这是你的脚本的头部，声明flag = false，然后检查标志作为你的while循环中的条件，如

while guess !='' && flag == false:

在correct_letter()：

def correct_letter(guess):
    guess = guess
    if letter_guess(guess) == True:
        print ('Correct: ' + guess)
        flag = true
    else:
        wrong_letter(guess)

如何关闭我的'while'循环，以便程序不会无限循环？
