 From what you write here, I'm not exactly sure what you want to achieve, 
but...

Assuming that Python is installed on the machine and readily runnable from 
the PATH, this will make the script executable:

     #!/usr/bin/env python

     import os
     import math
     ...

Note that the file must have the executable bit set.

Search for "shebang", which is the spelled-out name for the "#!" special 
file prefix.
