Well, yes, but the Python VM is also written in C, and every time you
make a call to a dictionary, or list etc, it is C code which is doing
all the work. If you like, you could say that Python is a set of
extremely clever wrappers around a bunch of optimised C code - but that
rather diminishes the achievement of Python. I dare say that the
Microsoft .NET and Visual Basic VMs are also written in C/C++, so you
could say the same things about them - but I don't think that is a
useful perspective.
