Not necessarily, you need to put both example.py and _example.so in your
PYTHONPATH. If you are just testing, you can use any directory. So what does
this mean for you? You need to:
cd /path/to/dir/where/example.py
cp build/lib-something/_example.so .

Now you should be able to just 'import example'. You may want to look at the
attached setup.py and the python documentation for distutils (
http://python.org/doc/2.1/dist/dist.html ). setup.py is for a custon C wrapper I
use for a few libraries.

How did you expect to access the functions ?

True, again SWIG assumes that you will access them via example.py.

This would seem to be the expected behavior -- you access them in python, just
the same as you would in C.

Refer to the above remark, this should help.
