[Python] member functions in a class

No code is duplicated. 50 "objects" are created. Each object has its own
copy of the data attributes, and a reference to the (one and only) class
object where the method attributes are located.

That's a short answer. Perhaps too short?

Gary Herron

To expand slightly on Gary's answer. Dotted names -- ob.attr -- are
typically (but not always) resolved as follows: does ob have attribute
attr? If yes, get the corresponding object. If no, does type(ob) have
attribute attr? If yes, get the corresponding object. In no, look in
the baseclasses of type(ob) in some order (details not important here).

So, instance methods are class attributes and instance.method will
resolve to the method attribute of type(instance) -- assuming that the
instance does not have an attribute of the same name. Lookup for
special methods (with reserved __xxx__ names) may go directly to the
class and never look at the instance attributes.

Gary,



No the answer is not too short, thank you for your reply, I am learning
rapidly.



Terry,



The expanded answer is also useful. Now I am getting a better insight on
how python resolves object attributes.

This also gives me more insight on the difference between import <libname>
vs from <libname> from *.



Thanks
