Typing Module
The ‘typing‘ module is a built-in Python module that provides support for type hints.
Type hints are a way of indicating the expected type of a variable or function argument, making your code more readable and maintainable.
Additionally, the ‘typing’ module includes a number of classes and functions that allow you to specify types, such as ‘List’, ‘Tuple’, and ‘Union’.
_specialform attribute
The ‘_specialform‘ attribute is an internal attribute used by the ‘typing’ module.
It is used to represent certain special types, such as ‘Optional’ and ‘Union’.
These special types are used to specify that a variable or function argument can have multiple types, or that a variable or function argument is optional.
