That sounds quite right.  Check out
<URL:https://projects.scipy.org/scipy/scikits/browser/trunk/openopt/scikits/openopt/solvers/optimizers/optimizer>
<URL:http://svn.scipy.org/svn/scipy/trunk/scipy/stats/models/>
for examples that may be relevant to your project.

Python does not have interfaces per se, but that does
not stop you from designing interface-like classes and
inheriting from them.
