You're retrieving a "directory", a list of all of the stuff that's available in some resource.

Answer 2

Answer 3

This answer will be most useful to those new to Python.

I am learning Python and just this morning was thinking about the builtin constants and functions that are available in the language.

I find it interesting that you only have to remember three things:

There is a 'special' builtin function dir().

There is a 'system variable' __builtins__.

dir(__builtins__) outputs a view of 'Python's builtin world'.

So what does dir mean? I've settled on this for now:

directions: supplies maps for traversing the Python Landscape.

So if you want, you could also let dir stand for

display inside rubric

Answer 4

IIRC I named it after the DIR command in DOS.
