Gary's stats module is excellent and is probably sufficient for the uses
you
describe. There are also some elementary statistical functions in Konrad
Hinsen's
equally excellent Scientific Python package - see
http://starship.python.net/crew/hinsen/scientific.html
In fact, you could just use NumPy (Numerical Python) - have a look at
the MLab
module in NumPy (which is at http://www.pfdubois.com/numpy/ ).
However, if you are interested in more advanced statistical analysis
and/or in
drawing statistical graphs, then have a look at RPy, by Walter Moreira,
at http://rpy.sourceforge.net
RPy embeds the R stats environment within Python. R is good for most
things
statistical, from the elementary to the advanced and experimental, and
it does
truly beautiful graphics. It is a mature project backed by a number of
eminent
statisticians in five continents.
Note that R is multi-platform (see http://www.r-project.org ) but RPy
only
works under Linux and Unix (and Mac Os X, perhaps) at this stage. I
believe
a Windows version is in the works.
