Rule Engine in Python

[Lee Ingram]

I have used Google to scour the web looking for an implementation of a
rules engine using Python. I need a mechanism whereby slightly trained
end users will be able to add / modify business rules and have them
execute. I previously used Blaze Software's Advisor rules engine to do
something similar. Has anyone seen, implemented, or tossed out this
idea previously?

Inquiring minds want to know...

TIA
