О пакете: Null values and sentinels like, but not, None
Описание:
Helps define "null" values and sentinels parallel to, but different
from, None.
None is a great sentinel value and a classic implementation of the null
object pattern.
But there are times that you need more than one nullish value to
represent different aspects of emptiness. "Nothing there" is logically
different from "undefined," "prohibited," "end of data" and other kinds
of null.
The core function of nulltype is representing emptiness and falsity in a
way that doesn't overload None (or False, 0, {}, [], "", or any of the
other possible "there's nothing here!" values). It helps create
designated identifiers with specific meanings such as Passthrough,
Prohibited, and Undefined.
