Python was installed on the d0sgi's by scott, and I know of a few examples 
which I got from the web which might be interesting to look at. Scott may have 
more. Here's how it works for me:

setup tcl
setup tk
cd ~lueking/python/temp
setenv TCL_LIBRARY $TCL_DIR/tcl/library
setenv TK_LIBRARY $TK_DIR/tk4.0/library
python pong-demo-1.py
  ... and lots of other *.py demos 

There is also a ps manual in ~lueking/python/Doc/tut.ps
