Question

Instead of using IDLE, would this course allow me to use Sublime 2 along with the MacOSX terminal?

Answer 1

as long as you can write, run and validate the code you can use anything you want

Answer 2

You should be fine. You don't have to follow things ACTUALLY how you see them. It's best to make the course work for you, best way you know how.

Answer 3

IDLE is just a development environment you can use to write code. You don't necessarily need the same development environment, or even need a development environment at all.

Answer 4

The only requirement for an editor is that it produce plain text ( no formatting bytes ). After that there are dozens that are suitable.
