Python virtual environment

Used Python virtual environment for the 1st time. It seems that none of the documented way to do this was an exact fit for me…odd. Seemed like a good way to try out the new version of the reportlab PDF module and also add the PyPDF2 module to get rid of the first blank page. Seemed to work well once I figured out I had to run (in my virtual environment) my program like ‘python3 program_name.py and not ./program_name.py (which ran the non virtual program).
