Constructor of object

Isn't it the other way round ?-)

First point : __init_ is *not* the constructor. It's the initializer. 
The constructor is named __new__. You'll find more about __new__ here:

http://www.python.org/download/releases/2.2.3/descrintro/#__new__

Second point: 'self' is just an ordinary local variable. So rebinding it 
has no effect outside the function.

> but it not work, because "object not initialized". What i can do?

Learn to post a full traceback ?-)
(Sorry, just kidding.)

FWIW, I don't know which problem you're trying to solve this way, but 
there may (conditional...) be better solutions. Like using a factory 
function...
