Why is it that (nearly) every description I read about some random new Python command wrapper fails to get the "python" and ".py" out of the command examples, even in Linux?
I don't blame this particular offering, since I don't think release was actually planned just yet and any number of other projects have made the same subtle mistake.
Command Name Extensions are Harmful. Don't expose such an implementation detail in every example, lest everyone actually follow them. Use the "#!/usr/bin/env python" or whatever at the top of your scripts. And yes, you can keep the .py if what you have is a library, not just a command (but it's nice to then make a wrapper the doesn't expose the implementation language). And obviously in other OSes where the command extension can be omitted and still work this isn't such a big deal.
But in Unix/Linux, commands should be reimplementable in a different language without making some .(extension) a like, retained to keep from breaking other things that depend on it. Just say no :-)
It actually shows you how to set it up so you don't even use a #!, but rely on setuptools to make an executable for you, that'll work in a vitualenv or on windows. And the script name doesn't have .py at the end in his example, though he doesn't call that out specifically.
