Unfortunately, you're not describing a droplet, but only the usual 
Windows file association scheme.  (Incidentally, the OP was asking about 
the Mac)

The filename that goes into the %1 of the shortcut is the name of the 
script.  So that will show up in sys.argv[0].  The OP wanted to drop a 
data file, and have its name show up as sys.argv[1].

I don't know the Mac, so I stayed out of this thread.  But I haven't 
found any way to do real Python droplets on Windows.  Closest I found 
was adding my python app to the right-click menu, so one can right-click 
on a data file to get the Python code to run on it.

What a droplet needs is for the user to be able to drag a data file to a 
python script, and have the script start, with sys.argv[1] pointing to 
the data file.   I'd love to know how to do it in Windows, and the OP 
would love to know how to do it on the Mac.
