Python怎么设置按任意键退出

import msvcrt print("Press 'D' to exit...") while True: if ord(msvcrt.getch()) in [68, 100]: break

这样，当用户按下“D”或“d”时，则程序退出。

while True:

    input = raw_input('请输入: ')

    try:

        input = int(input)

        if input%2 == 0:

            print input," 是偶数:"

        else:

            print input," 是奇数:"

    except:

        input = str(input)

        if not len(input):

            inputExit = raw_input('Y退出，N不退出:')

            if  str(inputExit) == 'Y':

                break

            else:

                continue

        if not ' ' in input:

            print input,"是字符串，长度为:",len(input)

        else:

            print input,"是一句子，共有",input.count(' '),"个空格！"
