This is ancient, ancient history (Nov 1998 ancient), but I get
the occasional request for it (still). The legacy python.org
website has the proceedings of the Seventh Python Conference.
It has my paper in both HTML
and PostScript form,
but I also gave a short talk.
Someone asked about persisting functions
from Python's REPL. This little module
doesn't do exactly what they wanted, but I use it on
occasion. It could be augmented to save to a user-defined file
with little effort.
Back in the dawn of time, I wrote a simple finite state machine module. I have no idea if it still works, but Google's crawler has been looking for it for some reason...
For Internet archaeologists, there are more Python bits on GitHub here and here.
