I'm not going to say it can't be done, but it's not something you're
going to do cleanly, and unless you've got a very good reason to do
otherwise, you're probably best to using Python if you're using a
Python Framework, or if you want to write in Ruby, then switch to a
Ruby framework.

Having that said, there are ways to call functions in one language
from another. A simple ( and inefficient ) way to do this would be to
just execute the interperter with the correct arguments. Eg to call a
function from a Perl module you could execute "perl -MSomeModule.pm -e
'some_function($some_argument)".

RPC/IPC would be another possibility where you run your ruby code in a
separate process ( except in this case a long-lived process ), and
communicate with it telling which function you want called, and it
would respond with the functions output.

Another possibility I've seen in embedding a Ruby interpreter in the
Python Interpretor. I haven't seen ( uncle Google may help here ) any
case of this for Python and Ruby, but here is a list of addons for PHP
which support writing code in other languags.

Having that said, unless you have a good reason ( and IMO preference
for one language isn't good enough ), this isn't a rabbit hole you
want to go down.
