I've used Jython successfully on OS X 10.1 in the past to do real work.
Though I mostly ran it in the Java debugger as a convenient shell for
probing Java classes.

It works really well with the OS X development environment as a default
class when doing Java development: just add the jython.jar into the
CLASSPATH of your project, set 'org.python.util.jython' to be your default
class, set breakpoints, run project, instantiate objects, call methods, and
see what happens. Very cool.

I just tried installing it again under 10.2 to see how it runs:

% ~/jython-2.1/jython pystone.py
Pystone(1.1) time for 50000 passes = 11.28
This machine benchmarks at 4432.62 pystones/second

Not *too* shabby (for comparison with standard Python see below).

Yup:

% /usr/bin/python
Python 2.2 (#1, 07/14/02, 23:25:09)
[GCC Apple cpp-precomp 6.14] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> 
% /usr/bin/python pystone.py
Pystone(1.1) time for 50000 passes = 6.51
This machine benchmarks at 7680.49 pystones/second

It appears to be a non-framework build, but it does have the Mac extension
modules as far as I can see.
