To expand on JR's answer and identify your misconceptions:
> In python each new instance of a class is created by __init__
No, instance is first created by internal default constructor or
new-style user-supplied equivalent __new__(). Then __init__ is
called, if it exists, with new instance as first arg to initialize
that new instance.

__init__ is called as a proceedure -- *any* return is ignored
