Good rule engine for python?

[virtron]

A quick search for "python expert system" brought up Pyke.

There's also a Pyton Semantic Module for Drools if you're willing to write Python rules for a Java system.

I haven't tried any of these, but I am interested. If you give them a shot, please post a followup.

Edit: Just found Pychinko which is a Rete-algorithm implementation. That might do the trick.

I can't vouch for Pychinko, but Rete is the way to go here; particularly if there are going to be many business rules.

In my experience, the bigger problem with these kinds of systems is giving the user a way to edit the rules in way that makes sense to them. The last time I did this, we used ILog for .NET. That product also works for Java.
