How do I use IDLE on Mac?

Question

I have installed IDLE etc from the Python website as instructed in the Python course. I got a warning when I opened IDLE
(WARNING: The version of Tcl/Tk (8.5.9) in use may be unstable. Visit http://www.python.org/download/mac/tcltk/ for current information.)
So I installed TCL as well. But now what am I meant to do with them? None of it seems to do anything. I have typed the print instruction into IDLE but it does nothing. Is there some extra trick I need to know if using these on a Mac?
For now I'm just going to use the Terminal provided by Apple, but I want to be able to follow the course as they instruct.

Answer 1

What version of Python are you using? I have 3.6.0 and Idle works with no problems. You might try upgrading the version of python to 2.7 or above and see if that works.

Answer 2

The same message appeared to me and it worked just fine. Open IDLE, click file, new, and then type in the new window called 'Untitled'. That's what worked for me.
