New submission from Yurii Karabas <1998uri...@gmail.com>:
Basically, the idea is to add the ability to mark abstract classes as strict. What does this mean - in case when a class inherits from a strict abstract base class and doesn't implement all abstract methods then it will fail to create a class. For instance: >>> class Iterable(ABC, strict=True): ... @abstractmethod ... def __iter__(self): ... pass >>> class MyClass(Iterable): ... pass TypeError: Can't create class MyClass with unimplemented strict abstract method __iter__ That allows creating abc classes and be sure that class defines a required method, it will be perfrormed on a class declaration stage rather than class instance creation. ---------- components: Library (Lib) messages: 387169 nosy: uriyyo priority: normal severity: normal status: open title: Strict ABC classes type: enhancement versions: Python 3.10 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue43243> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
