Correct. Aside from re-classing of user-class instances, Python
objects are more strongly typed than C values.

No, quite different.  A C cast (at least usually) recasts a block of
bits in a new role without changing the bits.  Type constructors
(unless redundant as in int(1)) return a different object with a
different set of bits.
