虽然循环没有正确终止

Question

所以我得到了这个代码，它会猜测 0 到 100 之间的数字。 它提示一个数字，用户用'h''l'或'c'回答

现在一切正常，除了我希望此行仅在用户输入不等于“h”、“l”或“c​​”时显示，而不是现在即使我输入“c”也会显示它会中断循环，对吧？

print "Sorry, I did not understand your input."

完整代码

start = 0
end = 100
guess = int((start+end)/2.0)
print "Please think of a number between 0 and 100!"
print


x= 'n'

while x != 'c':

    print 'Is your secret number ' + str(guess) + '?'
    x = raw_input("Enter 'h' to indicate the guess is too high. Enter 'l' to indicate the guess is too low. Enter 'c' to indicate I guessed correctly.").lower()
    if x == 'h':
        end = guess
    elif x == 'l':
        start = guess
    else: 
        print "Sorry, I did not understand your input."
guess = int((start + end)/2)

print 'your answer is: ' + str(guess)  

所以为了澄清这是即使我输入'c'时的输出

Enter 'h' to indicate the guess is too high. Enter 'l' to indicate the guess     is too low. Enter 'c' to indicate I guessed correctly.c

Sorry, I did not understand your input.

你的答案是：50

Answer 1

'c' 的情况没有elif，所以它属于最后的else。

添加以下内容来处理这种情况并打破 while 循环：

elif x == 'c':
    break

此外，您可以只执行while True: 并循环直到c 中断。

你的高/低逻辑也是落后的。对于h，例如 start = guess。

guess 的更新应该在 while 循环内缩进。
