Python and Computer Algebra Systems --- is it done?

[jm7potter at hotmail.com]

Hello all,

I am new to Python and this may be old news to everyone else,
but here goes.

I would like to use Python to do symbolic calculations like one may do
with Maxima, Derive, Maple, Mathematica, MuPad, or other such 
packages.

I do know that Scientific Notepad uses the Maple kernel or the MuPad
kernel to do the actual math work. Perhaps Python could use the Maxima
kernel? 

The question is really --- has anyone yet used Python to do any
symbolic math?

Thanks in advance,

Joe Potter
