Can you reference a class inside of itself in Python?

If I have classes A and B, I basically want to do something like this:

class A:
    myDict = {A: 3, B: 2}

Since my reference开发者_如何学JAVA isn't in a function, the class hasn't fully loaded by the time I try to use it. How can I get around this?

The proper solution is to move the dict outside the class

class A:
    pass

A.mydict = {A: 3, B: 2}

which will result in exactly the values you would get if you could do what you ask for.
