I suggest that you add     usr bin env python   instead of    usr bin python at the top of the file  The reason for this is that the python installation may be in different folders in different distros or different computers  By using env you make sure that the system finds python and delegates the script s execution to it   As said before to make the script executable  something like   chmod u x name of script py   should do
