In writing out python classes, it seems the 'self' is optional, meaning
that inside a class method, "self.foo = bar" has the same effect as "foo
= bar". Is this right? If so, it seems a little odd- what's the rationale?
Or am I mistaken?
Inside a function or method "foo = bar" would make "foo" local by
default. In an instance method an attribute "foo" of the instance needs
a reference to the instance itself, by convention "self", therefore
"self.foo". In a class method a reference to the class itself is by
convention "cls", therefore "cls.foo".
