I would simply add that if your python script produces one or
more output files (for example a text or graphic file) you
might want to have an 'output' directory in your project.

Some people use a 'src' directory, but that is not nearly as
neccessary as in a complied language.

In Eclipse, if you do produce output files, make them
auto-refresh.
