AleNone (AleNull)

AleNone (or AleNull) is a term used in programming, particularly in languages like Python, to indicate the absence of a value or a placeholder when a value is not provided. It is similar to saying "nothing here" or "no data." AleNone is represented by the keyword `None`, which helps programmers manage situations where a variable might not have a meaningful value yet. This concept is useful for controlling program flow and avoiding errors by explicitly showing when data is missing or optional.
