True, False with itnergers, strings Using bool() Why use bool()? Because all built-in types have bool because all built-in types are instances of class of str, int, etc
bool(1) True bool(0) False bool(345354) True bool("czxc") True bool("")
False x = "foo" bool(x) True
All built-in types have a bool(""). Because all built-in types have bool because all built-in types are instances of class of str, int, etc

More testing x = foo x has multiple built-in functions that we can check with dir()

Checks for draw() before isWin() Problem here is game calls draw instead of win Running updated_board() This is the current board. |X|O|X| |O|X|O| |O|X| |
isWin() is running. They say the only thing you can do is keep going. So... keep going? Enter your move: row, column 2,2 Running updated_board() This is the current board. |X|O|X| |O|X|O| |O|X|X|
