Answered 2019-Jul-08 at 15:06When looking up the value of an attribute, self.foo
will fall back to type(self).foo
(roughly speaking) if there is no instance attribute named foo
.
When setting a value, though, self.foo
will always update (or create, if necessary) an instance attribute. You have to explicitly refer to the class to modify a class attribute.
In your other example, self
"worked" in the sense that you verified the value of the new instance attribute inVar
of uac
. The class attribute Geek.inVar
remained unchanged.
