As Ivan said earlier, perhaps the Windows installers should provide a "python3" executable, so "python3 -m pip" works everywhere. absolutely! I really, really thought it did!!!! (I'm amazed I never heard from a single student getting bit by that...) On Windows, use py -X.Y to select the exact version of Python you want. Maybe Unix should have a launcher like this, too? It doesn't really need to be any more complex than Native UNIX packages have been using `pythonX' and `pythonXY' for years, with incomplete names meaning "the latest installed version qualifying". This allows very convenient and reliable use in shebangs -- the script explicitly states which version it is written for (and even which installation, by specifying a full path - then even e.g. overriding `python' on PATH doesn't break system scripts).
