Running Python Web-Servers

There are basically 2 ways which I have learned so far
1. You can run internal python web server

     python.exe -m http.server <8888> --port number is optional.. default is 8000

2. Using Flash web server, and to run that simply call python.exe <python file of flash>. please see below

PS C:\Mandar\Projects\RaterMigration\IhExpressToCogitateRater> python.exe app.py

   Use a production WSGI server instead.
