Let me clarify that just a bit.
There are several ways to run Python scripts from a Windows command line.
You can invoke the interpreter specifically by name:
 C:\Apps\Python27\python xxx.py
 C:\Apps\Python27\python xxx.pyw
Or, if the Python directory is in your path:
 python xxx.py
 python xxx.pyw
If the .py and .pyw extension are registered using assoc and ftype (which
the Windows installer does), then you can invoke them by file name:
 xxx.py
 xxx.pyw
If you add those extensions to PATHEXT, then you do not even need to
provide the extension, so they will look just like any other automatically
executable program:
 xxx
