dos2unix is handy if you don't plan to edit the file for any other reason.  I'm assuming other editors provide similar features, but I've been a vi/vim user FOREVER.

My question is this: Would it be good practice for him to put 
#!/usr/bin/ env python at the top of his scripts, so that if made 
executable on *nix they will be OK? As I understand it this will 
have no effect on Windows itself.


        

        
Adding the shebang line on Windows would be excellent practice.


      

      
A word of warning unless this has since been resolved: Whenever I have tried adding the shebang line on Windows and running it on Unix the latter has complained about the carriage return at the end of the line. This means that Unix does not work when invoked as follows.
(And, yes, the file has had chmod +x applied.)

  ./program.py

It is, of course, OK when run as

  python program.py

but that removes some of the benefit of the shebang line.
