Referring to method of a class without instance?

[gmol at my-deja.com]

In my application I use the observer/observable pattern..question
I hate duplicating the information of what was changed by making up a
new message type (global message variables or strings) and using tonnes
of if-else clauses.  I'd rather just tell my observer which method was
called and the arguments passed to it.  (I.e. I have atoms in 3d space,
when setPosition(position) is called I would just like to tell whoever
is interested that setPosition was called with the argument position))

Problem, how do I refer to the method of a given class without making an
instance?  Like suppose I notify my observers by giving the funciton
address and arguments, I would like the observer to have a dictionary
whose keys are methods

class Atom:
....


class myobserver:
...

   updateTable={....
       Atom.setPosition:handle_A_setPositio
    }
...

Hmm I have also just realized that given
class A:
 def __init__(self...)

a=A()

a.init is not equal to A.__methods__['__init__']

Hmmm I thought that would be the worst way I could do it, but I guess I
couldn't if I wanted to...

Any thoughts or better general solution would be appreciated...
