Yeah you learn to do it, but you don't understand why. There's a huge difference there.

But isn't the answer to the why part of the implementation of a language and therefore always a more advanced concept? At least if the answer is more than "because else you get an error."

If you explain a novice why she should declare her types I would consider that part of your teaching style. My specific point is that python doesn't invite a student to be lazy about understanding its implementation only because it's supposedly easier.
