These are examples of the results after running the py_who.d script.

This script shows which UIDs and PIDs are running Python programs with Python 
provider support, and how active they are.  It lists the name of the program, 
along with the number of lines executed per program as recorded by the line
provider.

Here it runs as the Code/Python/func_abc.py program is executed.

You can see that the program itself had four lines executed attributed to it,
and the other lines in the program were associated with their particular
Python library calls.
