OK. I had assumed, since it returned an object, that I could call a
function and get back the python result. I didn't use eval, because eval is
restricted to 1 expression, and so couldn't do something like:

import module
module.F (3)'''
which is what I was trying to do
OK. If you want to do this once, this seems a good approach. However,
for doing it repeatedly it might be better to first execute the
"startup" code, such that "module" ends up in a dictionary ("global", in
my case). Then you can run eval() on the expression you'd like to get
the result of:
exec(code, global);
for(...)
{
int result = extract<int>(eval("module.F(3)", global));
...
}
Thus you only need to execute common startup code once.
