I think that Python has inherited a lot (but unfortunately not all) of the artistic qualities of Lisp. So in a sense the artistic dynamic approach of Lisp won given the popularity of Python.
You can do introspection and access the variables at runtime (using a horrible syntax), but that's it.
I don't see much artistic aspirations in the language or in its creators. Ruby already has a much better metaprogramming story and the code looks more elegant.
