[Tutor] want to implement Workflow engine using python

[karthik Guru]

hi all,

I want to do a full fledged project to come to grips with this language.
Though i have managed to learn the features, i realize i w'd be in a better
position
if i do a project.

Can someone point to some good sites which w'd help me to devise a work flow
engine.
I dont' want to provide any great features , simple ones do

Any tips? what all i might have to use in addition to core python?
Database for sure...xml?

thanks for the help,
karthik.
