Why are monster, door, and player initially set to None?

var moster;
var door;
var player;
In Python it would like this:
moster = None
door = None
player = None
This will create the variables, but they won't have a starting value.
Just keep learning Python and you'll see this is helpful in some cases.
I hope this helps. ~Alex
