That won't work on Windows.

You have to define what do you mean by "a file is set as executable" 
on Windows.
a.exe is executable and nobody would discuss that. I can supress the 
extension and type simply: a, on the command line, and get a.exe 
executed. Same for a.com
What about a.bat? cmd.exe is executed and runs the batch file. I can 
even omit the extension. Is a.bat executable then?
What about a.py? Another process starts and handles the file 
(python.exe). Is a.py executable then?
I can type a.mdb on the command prompt and launch an Access 
application. Is a.mdb executable then?
If I type a.doc on the command prompt, Word is executed and opens 
that file. Is a.doc executable then?

The answer may be so narrow to just consider .exe .com and a few 
more, or so broad to consider all things that os.startfile can handle 
without error.
