title: Make a python script available to other person
body: <p>I have a python script that, in short, take some information from a xls file in the same directory and, based on that information, send some e-mail and update the xls file.<br>
  For my purpose sometimes I also have to manually update the xls file.<br>
  I would like to make this script available for a friend.<br>
  The best thing would be that he can manually update the file and then execute the script, better if he doesn't have to install python. Is it possible?</p>
