Steven touched on this, but I'd like to emphasize: in Python, EVERYTHING is
an object - variables, functions, integers, strings, you name it.  (Even
names and namespaces, but that might be getting a little TOO meta.)
When I first came to Python, after years of languages where some things are
objects and other things aren't, this concept gave me a little trouble;
once I got my head around it, namespaces made sense too.
