Set up Python on Windows to not type “python” in cmd

by 
C:\> assoc .py=Python
C:\> ftype Python="C:\python27\python.exe %1 %*"

Or whatever the relevant path is – you can also set command line args using ftype.

In order to make a command recognized without having to give the suffix (.py), similar to how it works for .exe files, add .py to the semi-colon separated list of the (global) PATHEXT variable.

Seems like this is still getting eyeballs, wanted to elevate a useful comment for Win10 users (from @shadowrunner):

For me to get it work under Win10 the actual command was (note the placement of the quotes): 

C:\> ftype Python="c:\Anaconda2\python.exe" "%1" %*

Talk about evergreen!

First of all, if you’re newly installing Python, I highly recommend reviewing the answer by @NunoAndré .

Secondly, to clarify something from a recent comment, please note: you must do both parts (assoc and ftype), or use a pre-existing association label in the ftype command.

By default, at least for Python 3.7 under Windows 8.1, the association for .py is Python.File, so performing the ftype command I wrote above will not work correctly unless the association is first changed. Or you can just use ftype and give the default association instead. Up to you.
