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.<br>

Adding the shebang line on Windows would be excellent practice.

<pre wrap="">
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.
