It only happens if you try to *bind* the name "jj" to an object inside 
the function.

My guess is that you have a C/C++ view of variables and values, where 
variables are locations in memory that can hold values.  In Python, such 
locations are called objects, and they may or may not have names bound 
to them (via assignments).

This might help:

Then read

     http://docs.python.org/ref/objects.html

and finally read the "Naming and binding" page again.
