[Windows] drag-and-drop onto .py file in modern versions?
Hello all,
Back when I had 2.6.x installed, I used to be able to drag a file onto a
.py file in order to open it with that script (rather, pass the name of the
file as `sys.argv[1]`). I did nothing special to make this work, as far as
I can recall; it was something that the installer set up automatically. I
am running Windows Vista.
Now that I have uninstalled 2.6.x, and have 2.7.2 and 3.2.2 installed, this
behaviour no longer works. The .py file is apparently not recognized by
Vista as a valid drop target; it does not highlight, and when I release the
mouse, the dragged file is simply moved to / reordered within the
containing folder.
I was able to find a registry hack that is supposed to re-enable this
behaviour:

However, I tried this and it had no effect whatsoever.
Is there any way I can get the drag-and-drop behaviour back? Was it
deliberately disabled for some reason? It was exceptionally convenient for
several of my scripts, and now I have to make .bat wrappers for each one to
get the same convenience.
Aside: when I double-click a .py file, what determines which Python will
run it? Is it a matter of which appears first in the PATH, or do I have to
set something else in the registry? Will a shebang line override the
default on Windows? If so, how do I write a shebang line for a Windows path
- just #!C:/Windows/Python32?

The file-type association (which is really a file-extension association) determines the path to the executable. If that's specified without a full path, then it'll be the first one in PATH, but usually the association is given as an absolute filespec. I don't have a Vista handy, but in XP, bring up any folder, Options|Folder Options, File Types, and scroll down to PY. (For some obscure reason, on this particular computer of mine the association is with a Python that was installed with GNU Lilypond. Weird!) You may need to use the Advanced button to see the full path. As to writing a shebang, there's no way to do that directly. But in theory you could associate .py files with a little script that reads the first line and figures out which interpreter to invoke it in. For extra coolness points, write that script in portable Python that can be run on any of the interpreters you have installed - then you don't have to care! :) Chris Angelico -- http://mail.python.org/mailman/listinfo/python-list
