Random Walks in python

There are classes for Location, Drunk, and Field. I was trying to have a subclass dirty field. That generates a dirty tile in the field. If a random walker moves on the dirty tile then, they keep moving.

I am getting the following error: I am hoping that y'all see something that I don't see. edit: I have fixed the grammar errors and now when running I am getting a randint() error. When looking into randint should I change it to uniform?
