Why 'none' is considered special in python???

None is just a value that commonly is used to signify 'empty', or 'no value here'. It is a signal object; it only has meaning because the Python documentation says it has that meaning. There is only one copy of that object in a given Python interpreter session. If you write a function, and that function doesn't use an explicit  return  statement, None is returned instead, for example. That way, programming with functions is much simplified; a function always returns  something, even if it is only that one None object.
