I think Python is among the best languages currently available to teach programming (Python partially comes from ABC, a language mostly designed for teaching), but it's far from perfect still for this purpose:

What kind of problems? (related to tabs vs spaces?)

Yeah, I personally don't like dynamic typing at all.

I strongly disagree. The first language they learn should *not* be
agnostic to case, so they learn that case matters (because it does in
most languages).
