what is a function object?

[zakons at my-deja.com]

Hi,
I use function objects for sorting lists and they are great but I want
to know more about what a function object is in the python environment.

* How is a function object different from other python objects? What
does it include extra? What is missing?

* How may function objects be accessed by name in various namespaces?

* Other than for sorting, what are typical uses of function objects?

* What does it mean to say that function objects are first-class objects
in the python environment?

Thanks,
Stuart Zakon
