None Type

In programming, "None" is a special value indicating the absence of a value or the lack of any meaningful data. It’s similar to saying "nothing" or "no value here." For example, if a function in a program is supposed to return information but doesn’t find anything to give back, it might return None. It helps programmers understand whether a variable has been set or if a process has produced a result. Think of None as a placeholder that signifies "nothing" rather than an actual piece of data.
