I'm new to Windows 7 and with my Python installation. When I specify in cmd.exe and hit Return/Enter, instead of executing the python file, I am given an error message (sth like "not a command").

How do I tell Windows to run the Python interpreter when specifying or double-clicking a Python script?

Associate the .py extension with the python.exe interpreter executable. Normally the installer does this for you.

I'd rather suggest to associate the .py extension with the pythonw.exe by default, to anticipate the question "It works now, but I don't want to see that cmd window." – vtest Jun 22 '10 at 11:21
