I agree, for deployment to environments where you can guarantee that the basic Python infrastructure is available. It may not be though, and perhaps we can relegate that to py2exe, cx_freeze, and friends, although I would say that having such support built into Python would be very cool, and of high value to our users. That's not to play down the usefulness of good executable zip support, pared of the stdlib and interpreter. OTOH, it would be nice to think ahead, where the same tool could generate both types of single-file executables. >Handling of C extensions in zipfiles isn't so much an executable zip >issue as a zipimport one. Agreed. >(Although promoting the executable zip format would help persuade projects to >*use* those features rather than assuming a filesystem). Donald Stufft has a >proposal on resource APIs for importlib that would help with this. Yep, which I support. :) pkg_resources.resource_filename() is the way to do that today and it abstracts away all the nastiness. Mostly agree with your other comments, though I haven't played with pyzzer and pex is quite nice, for the pared down use case, although it's not quite integrated with virtualenv (I've had some discussions with pex's author about that). OTOH, I think it *would* be useful to have this built into Python. We almost have too many choices, and may people I've talked to lately (including experienced Pythonistas) have trouble choosing the right tool. But that can come later; let's get some basic support into Python first, and a good start IMHO is executable zips (including support for extension modules) with the pkg_resources/importlib API additions.
