I think the PEP 328 relative import feature is likely to be what you want: you can specify that a specific import should search for the file relative to the current module's file, instead of from ‘sys.path’. As described earlier, by working through the Python tutorial <URL:http://docs.python.org/tutorial/> you will learn about the different styles of import statement, including relative versus absolute <URL:http://docs.python.org/tutorial/modules.html>. > But, I'm curious as to where the first bunch of 'site-package' entries > come from.

That's probably there because you have used the Setuptools system (or something related) to install a third-party package. That is achieved by meddling with the start-up module search path, to make the third-party package available for import. The result is often a messy search path. Python's system for installing third-party components is far from ideal; it has seen a lot of improvement recently, but on the other hand is carrying a lot of baggage from its earlier design. This is one of the symptoms. > Thanks for the education, I hope that helps! -- \ “To me, boxing is like a ballet, except there's no music, no | `\ choreography, and the dancers hit each other.” —Jack Handey | _o__) | Ben Finney -- http://mail.python.org/mailman/listinfo/python-list
