Looking for a text file based wiki system written in Python

[Jack]

I'd like to set up a wiki system for a project I'm working on.
Since I'm not good at databases, and there's really not much
stuff to put into the wiki, I hope it is text file-based.
I used DokuWiki before, which is very nice but it's written
in PHP. Is there a similar system that's written in Python?
I found pwyky but it's functionality is a bit too simple.
