Inside a method, including __init__, self refers to the object. Even
if you never assign it to anything, that instance exists somewhere,
and self can refer to it. It has an identity from the moment it begins
to exist - which is before it ever gets the name 'x' pointing to it.

You definitely should work through the tutorial I linked you to; it
explains Python's object model quite well.
