here's a good start:

http://www.nmr.mgh.harvard.edu/Neural_Systems_Group/gary/python.html
for some nice pure python statistical function implementations.

Orange, the super cool python machine learning system also includes an
extension called statc.dll which has some fast functions.

a data mining extension to orange for clustering and whatnot is also
available:

There is the fine and well-documented python Numeric library:

Scipy - scientific tools for python (includes a version of Numeric):

And, of course, there is Scientific Python:

all of these, like python, are fun, fun, fun...

enjoy (-:
