If the convention in Python is to capitalize classes, why then is list() not capitalized? Is it not a class?

Question

Often when I see class definitions class Foo:, I always see them start with upper case letters.

Answer 1

According to PEP 8, a nice set of guidelines for Python developers:

Almost without exception, class names use the CapWords convention. Classes for internal use have a leading underscore in addition.

PEP 8 is directed at Python development for the standard library in the main Python distribution, but they're sensible guidelines to follow.
