If this question means "Can I use Python instead of Emacs Lisp to add
extra modules to Emacs?", have a look at PyMacs :

If this question means "Can a running Python process control a running 
Emacs process?", then you probably want to use gnuserv.  This comes
standard with XEmacs. I do not know about the other Emacs.  You need to
get (X)Emacs to call the Elisp function "gnuserv-start", and then 
access
this process through the "gnuclient" program.  Here is an example:

 $ xemacs -f gnuserv-start &
