TIC TAC TOE GAME - python

Question

Я написал игру «tic tac toe» в питоне (pycharm). В конце игры я спросил пользователя, хочет ли он снова играть: если он нажал «y», игра снова началась, и если он нажал «n», игра/код остановилась. знаете ли вы, как я могу показать ему ошибку massege, например: «вы ввели неправильный ответ! Повторите попытку:« Когда он не нажимает ни одно из этих писем, а что-то еще? например: «Вы хотите, чтобы играть снова?„FNJ“(его ответ) и показать этот массаж, пока он не будет введен правильный ответ

Answer 1

if answer.lower() == "n": 
     print color.BLUE + color.BOLD + "Bye Bye! See you next time! :)" + color.END

     return False 
else: 
    print (color.BLUE + color.BOLD + """\nyou entered a wrong answer! please try again:""" + color.END) 
     return False 

Answer 2

Вы можете изменить функцию закончить следующим образом.:

def finish(): 

    while True: 

     answer = raw_input(color.PURPLE + color.BOLD + """Would you like to play again?! (press \'y\' for yes and \'n\' for no):""" + color.END) 
     if answer.lower() == "n": 
      print "" 
      print color.BLUE + color.BOLD + "Bye Bye! See you next time! :)" + color.END 
      return True 

     elif answer.lower() == "y": 
      print (color.BLUE + color.BOLD + """\nGreat choice! The game will start again""" + color.END) 
      return False 

     else: 
      print 'Not valid input...' 

к таким образом программа игнорирует недействительные входы и запрашивает у пользователя снова.

PS. Я хотел бы предложить, чтобы вставить механизм для выхода до завершения га мне в случае, если пользователь хочет завершить игру.
