Each language defines its own primitive types, some have no primitive
types (or hide them better), some are more primitive than others.  In
Python, complex numbers have an implementation which is coded in C and
quite fast compared to anything achievable in pure Python.

In the sense that they are not based on hardware-implemented types
that's true. In the sense that they are "special" in Python (i.e.,
faster and more efficient than user-created types), then they are
still primitives.

I understand that you're an inquisitive student, but the style you
respond in is often more aggressive than inquisitive, as far as I've
been able to observe.  Nothing wrong with challenging the status quo,
or whatever, but it does tend to squelch participation on the list at
times, especially from members who are less thick-skinned (or patient)
than Kirby.

Just saying.
