Almost.

Try this:

mydef.Fatalln()

Unless you import the symbols from your mydef module into your program
they have to referenced by the module name.  This is a good thing and it
helps keep your code separated and clean.  It is possible to import
individual symbols from a module like this:

from mydef import Fatalln

Avoid the temptation to import *all* symbols from a module into the
current program's namespace.  Better to type out the extra bit.
Alternatively you can alias imports like this

import somemodule.submodule as foo

Frequently this idiom is used when working with numpy to save a bit of
time, while preserving the separate namespaces.
