If I create a simple package consisting of a package/__init__.py containing: print "Package: "+__name__ import module and a package/module.py containing: print "Module: "+__name__ import package and zip the directory resulting directory up, then it imports fine if I add the zip to sys.path However if Instead create a zipimporter object and add it to the meta_path then I get a whole heap of recursive imports resulting in output of the following form: Package: package Module: package.module Package: package.package Module: package.package.module Package: package.package.package Module: package.package.package.module Package: package.package.package.package Module: package.package.package.package.module Package: package.package.package.package.package .... before finally running into an exception: ValueError: Module name too long For reference my version string is '2.3 (#46, Jul 29 2003, 18:54:32) [MSC v.1200 32 bit (Intel)]'

Logged In: YES user_id=92689 Hm, good catch! I don't see an obvious fix for this, and I worry that this is the result of a design flaw in the interaction between meta importers and path importers. For now, I think I should document that the zipimporter object is not suited for use on sys.meta_path. I need to do more thinking here.

The zipimporter is not designed to work on sys.meta_path, so closing as "won't fix".
