any multi-pattern mathching for python

[saddle]

as I know , agrep can handle this , at least the newer version from
http://www.tgries.de/agrep/index.html with a -f property.
here is a agrep port to python
http://www.bio.cam.ac.uk/~mw263/pyagrep.html, but it is some out of
date, and in it's discription "matching of multiple input patterns is
deferred to another day", after three years passed...,
could anybody give me an advice where has a implement of this multi
pattern matching style. thanks in advance
