Set up Python on Windows to not type python in cmd

When I use python on Linux, or even Mac OS from command line, I take advantage of the shebang and run some of my scripts directly, like so: ./myScript.py. I do need to give this script executable permissions, but that is all.

Now, I just installed Python 3.1.2 on Windows 7, and I want to be able to do the same from command line. What additional steps do I need to follow?

The Python installer should have associated .py files with the interpreter in the registry. You might have to manually add the extension to the PATHEXT environment variable. - martineau
@martineau Adding extension to the PATHEXT is needed only if one wants to run scripts without using extension. - Piotr Dobrogost
Did you try to run it the same way you're used to on Linux (by just typing myScript.py) before asking this question? - Piotr Dobrogost
@Piotr Dobrogost: Regardless of whether PATHEXT has had .py added to it and what that does, the important point is that in general one doesn't have to do anything after installing Python to be able to run scripts from the command-line (or by double-right-clicking on them. For that reason, I don't understand why the OP accepted the answer that they did. - martineau

This sums it up better than I can say it:

http://docs.python.org/faq/windows.html

More specifically, check out the 2nd section titled "How do I make Python scripts executable?"

On Windows, the standard Python installer already associates the .py extension with a file type (Python.File) and gives that file type an open command that runs the interpreter (D:\Program Files\Python\python.exe "%1" %*). This is enough to make scripts executable from the command prompt as foo.py. If you’d rather be able to execute the script by simple typing foo with no extension you need to add .py to the PATHEXT environment variable.
