# `none`
|

|
|
|
||
|
|
Python's null type, referred to when a null or "placeholder" is needed. It is in and of itself a singleton in any given interpreter session, so `None is None` is always considered True.
|
||
|
|
|
||
|
|
None is used in both [binary-search-tree][binary-search-tree] and [markdown][markdown].
