Python Special Literal

In general sense, Python special literals are reserved keywords which are used as literal constants. The typical Python special literals are boolean literals and none literal. These Python special literals are Python objects of class types.

Boolean Objects

Python boolean is implemented as a subclass of integer. There are only two boolean types, Py_False and Py_True. A Boolean literal can have any of the two values: Python True or Python False. True and False are simply built-in named values for the Boolean objects. True and False are defined as Boolean logic True and False. image

None Object

Python None is implemented as a subclass of integer. There are only one none type, Py_None. None is a special literal to name the Python None type class. None is simply a built-in name for the Python None object. None is defined as a null value, no value at all, or the object has not been created. To an object, empty is defined as a value with no element with reference to the object, while no value at all is defined as no reference to the object at all. image
