% exec env GRR="This is a late parrot." $SHELL
% echo $GRR
This is a late parrot.

Or you can use the script-generated shell commands approach, although
this is overkill unless you are trying to do something more complicated
(such as insert elements into PATH or CLASSPATH etc).

import os
m = { 'GRR': 'This is a late parrot.' }
if os.environ['SHELL'].endswith('csh'):
     for k,v in m.items():
         print "setenv %s '%s'" % (k,v)
     for k,v in m.items():
         print "export %s='%s'" % (k,v)

% eval `python_env`
% echo $GRR
This is a late parrot.
