You're using rather-advanced features, apparently; take care!

It's spelled __setattr__.  It's called, if it exists, each and
every time you set an attribute (either object.attribute=value
syntax, or setattr calls, but not with obj.__dict__['attr']=val,
which is what you may need inside your __setattr__ to avoid
accidentally recursing).

This is the semantics of __getattr__.

No, the rules don't change, whether __init__ is being executed
at the time, or not.
