If you were to read and digest what is written it would help.  You're 
trying to run IDLE.  We're talking the interactive interpreter.  If (at 
least on Windows) you run a command prompt and then type python<cr> you 
should see something like this.

Python 3.4.2 (v3.4.2:ab2c023a9432, Oct  6 2014, 22:16:31) [MSC v.1600 64 
bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.

My fellow Pythonistas, ask not what our language can do for you, ask
what you can do for our language.
