startPosition limited to only 4 cardinal directions?

It'd be more flexible if you could just enter the desired amount of degrees into setInitialPos() instead of only 'South', 'North', 'East', 'West'.
Maybe add another elif into that method like this:
`elif type(pos)==int:
            self.startPosition = pos * 16`

Asking because I'm looking to make smth similar to this:
