It appears that you are on a UNIX system.  Most systems will support
"shebang" proceesing of the first line in the file.  The first line tells
UNIX to find 'python' in the PATH and run it to exectute this script.  Use
'man env' for more information.

#! /usr/bin/env python
import os
import sys

When you do this, you do not need to uses the word 'python' on the command.
At the '$' prompt, just use:


The first line tells it to use Python to process the file.  Of course
/home/john where the script.py file exists must be in the PATH variable in
order to run it from anywhere.  Just like you have /bin in your PATH
variable already.
