Yes.

It's a reference to an instance of the ‘foo’ type.

That instance is also a namespace; in other words, its attributes are in
a distinct namespace from all other instances.

This is complicated by the fact that it *also* gives access to the
attributes of ‘foo’, shared by all instances of that type. But that's
part of what it means to be an instance of the ‘foo’ type.

It's *a* namespace. Since ‘one.x’ also presumably has attributes, then
it, too, is a namespace.


Learn more about classes and namespaces in Python's documentation
<URL:http://docs.python.org/tutorial/classes.html>.

In fact, you should work through the entire tutorial from start to
finish, experimenting manually with each example until you unsderstand
before moving on. That will give you a very solid grounding in Python.
