that's a module containing a class, not a "class file"

as you noticed, "import YourClass" gives you the module.

to get at the class itself, refer to it as "YourClass.YourClass"
(the YourClass object in the YourClass module).

you can also write "from YourClass import YourClass".

there are no such thing as a "class file" in Python.  just modules...
