Python Unbound Method TypeError

You reported this error:

TypeError: unbound method get_pos() must be called with app instance as first argument (got nothing instead)

What this means in layman’s terms is you’re doing something like this:

class app(object):
    def get_pos(self):
        ...
...
app.get_pos()

What you need to do instead is something like this:

the_app = app()  # create instance of class 'app'
the_app.get_pos() # call get_pos on the instance

It’s hard to get any more specific than this because you didn’t show us the actual code that is causing the errors.
