Hello Tom,

I don't know if this answers your question, but in order for a Python script
(or any script, really) to be executable under Linux (and all UNIX-like
systems), you need to do two things:

   1) Make sure that the file has the executable bit set.  This can be done
      with the chmod command, for example 'chmod +x'.  Be sure to
      read the man page for chmod, if you aren't already familiar with this

   2) At the very first line of your script file you must have a so-called
      shebang line.  This line tells your shell how to execute the file.  The
      Python tutorial recommends this shebang:

          #! /usr/bin/env python

      (No spaces before the # and the newline *must* be '\n'.  If you use
      '\r\n' it won't work and the error message isn't very helpful)

Alternatively, if you don't wish to do all this, you can also execute your
script by typing 'python'.  Regardless of which approach you take,
however, python must be in your $PATH for either of them to work.  If python
has been properly installed on your system, it will be.
