Hi Jim,
As Tyler mentioned, len is a convenience function that returns the length of
any object implementing an __len__ attribute. Typically that is a container
object like a list or dictionary.
del is a language keyword that unbinds a reference, the opposite of assignment
which binds a reference. Note it does not delete an object.
In Python, a file object is an instance of built-in type file . The built-in
function open creates and returns a file object.

Subject: [program-l] Silly Python Question
Hi,
I tend to obsess about things sometimes. I was looking at the Python Standard
Library documentation and reading about lists, dictionaries, and files, and I
started to wonder why len, del, and open are part of the built-in's, if that's
the right term, rather than methods of the objects called dictionary, list, and
file. Just saying.
Jim
