title: How can i "TIE" on my python TIC TAC TOE game
body: <p>I am figuring out how to tie the game. I'm having difficulties. Can anyone provide a code to replace it or fix it?. Thank You.</p>
  
  <p>I programmed a tic tac toe game in python and it works perfectly fine and everything. So i was wondering, can you somehow program the game to say, "Do you wish to play again?" after the computer wins or if you win?</p>
  
  <p>In my game, once the computer wins or you win, it doesn't say anything and i want the game to ask the player if they want to play again.</p>
  
  <p>Thank you.</p>
