I've just completed a Connect Four game and now I'm wondering how I can keep the board in one place without having it refresh over and over again in the console. I've searched far and wide on the web for any solutions but couldn't find anything.
Below is my full code. Feel free to run it on your IDEs. Any help would be greatly appreciated!

won it will return 'O'."""
