You do this in a console window, at a bash prompt.

You also need to add the "shebang" line at the top of the file.
That's a standard format comment line that Unix knows to look 
at to determine which interpreter to use to execute the script.
It's a Unix thing, not Python, which is why the tutorials don't say 
much about it, they assume you know Unix if you are using it.

Yes provided they use chmod on it too.

You can find more about the chmod and shebang stuff 
in the Style topic off my tutorial inside the Note for Unix Users 
near the bottom.
