Type Annotations

  • They add type hints to variables, arguments and functions ('def f() -> <type>:').
  • Hints are used by type checkers like mypy, data validation libraries such as Pydantic and lately also by Cython compiler. However, they are not enforced by CPython interpreter.

    Slots

    Mechanism that restricts objects to attributes listed in 'slots', reduces their memory footprint.

     __slots__ = ['a']
