Anyway, now you can see two batch files you could use to make a
particular version of Python active. The first one uses assoc and ftype
to fix the asssociations. And the other changes the environment variable
PATHEXT to make the extension optional. Note that changing the
environment variable is effective only for that DOS box, and its
children. If you want a permanent change, you need to change the
registry, probably at
hklm\SYSTEM\ControlSet001\Contro/Session\Session
Manager\Environment\PATHEXT
The better way to do this is to bring up the System control panel applet
(shortcut: WindowsKey + Pause/Break), Advanced, Environment Variables. In
the System variables, click PATHEXT and Edit, and add ;.PY;.PYW to the end.
Certainly that's how I'd do it. But the OP was averse to even using the
OpenWith dialog to change the file associations. He wanted a
commandline/batch/script way of doing it. So why would I give him the
same kind of an answer for modifying environment vars?
