How can I make a class that has methods with attributes and other

I see a lot of code


I'm reading the documentation to Redhat's Satellite software which = has a
XMLRPC interface and wrote the following code to test the api.

I would like to extend this code to support methods with methods? I see
this done a lot in python code but I'm not sure how to accomplish
something like this?

i.e.

sc =3D SatelliteConnect()
sc.get_systemlist().get_systemid() ?
or
sc.get_systemlist().get_running_kernel()

How does one chain methods and attributes like this with classes?

[snip]
This:

=A0 =A0 sc.get_systemlist().get_systemid()

simply means that the method "get_systemlist" returns an instance= of
some class (let's call it "SystemList") which has a method "get_systemid".
