General Hash Functions In Python

[Arash Partow]

Trial and error - how else? :)

I believe finding a perfect hash function for
every kind and combination of data is a very
very time consuming operation. Also there is
the common case where the data is online
(ie: stateless) that said it doesn't mean you
can't make assumptions about the kind of data.
