That's not quite accurate. In most dynamically-typed languages,
variables don't have types *at all*; types are associated with
values, not variables. If you took the above statement literally,
you might think that once you had assigned something of a given
type to a variable, you couldn't assign something of a different
type to it later -- which is obviously not true of Python (or
Lisp, or Scheme, or Smalltalk, or any other d-t language I can
think of!)
