Algebraic Data Types in (Typed) Python
“Algebraic Data Types (not to be confused with abstract data types) can transform certain types of invalid states from runtime errors into type-checking errors, making them an excellent method for representing data and managing state.”
The Different Uses of Python Type Hints
Python type hints can be used in five different ways: interactive programming help, static type checking, runtime behavior determination, documentation, and compiler instructions. Read on to learn more about each case.
