如何询问某人是否想再玩一次

Question

我不知道如何询问用户是否想再玩一次，如果他们说y 它会循环回到开始或n 并退出游戏，我不知道该怎么做。我知道我可以使用循环，但我不知道如何使用它们。

我建议你的是： 阅读 python 文档和函数式编程。之后，您可以使用此方法来获得理想的结果...

你可以从中得到启发：

#!/usr/bin/env python
import sys
import random

def play_game():
    print ' I am playing...' #Put your code here

def repeat(answer):
    if answer == 'y':
        print ' Good...'
        play_game()
    elif answer == 'n':
        print ' Exitting...'
        sys.exit()
    else:
        print ' Invalid choice!'
        return 'continue'

if __name__ == '__main__':
    try:
        play_game()
        while True:
            answer = raw_input(' Do you want to play again? [y/n]')
            ans = repeat(answer)
            if ans == 'continue':
                continue
    except KeyboardInterrupt:
        print '\n Ctrl+c signal recieved!'
        sys.exit()
