Question

A little background – I am playing around with pygame, and want to create a dictionary of all Mob class instances’ positions.

The way I see it:

human = Mob(pos)
mob_positions = {human : pos}

So every time I call Mob.__init__() I wanted to add a pos to mob_positions dict.

How do I access current instance variable name? Or is it extremely wrong approach?

Answer 1

The current instance variable is simply the first argument to the function. By convention it is named self.

Here’s how I’d do things.

class Mob(object):
    def __init__(self, pos, mob_positions):
        self.pos = pos
        mob_positions[self] = pos
