[Tutor] Command Line Editting: How to improve options?

[J L]

 Win 7Python v 3.4.3
I'm new to Python and only have coursework under my belt in another object oriented programming language as well as limited systems skills. 
After launching Python from the command line with py.exe, it appears that the interrupter starts up fine. I've read on Python.Org's site in a tutorial section that some interrupters offer command line editing beyond simple use of the arrow keys and backspace. It does not appear that my environment is allowing these greater abilities.
How does one afford increased abilities to edit commands within Python's interrupter?
Thank you.
