Final classes for python3.6+.
- No metaclass conflicts
- No runtime overhead
- No dependencies
- Type hints included, PEP-561 and PEP-591 compatible
- Designed to be as simple as possible
In languages like java we have a nice way
to restrict subclassing any class by making it final:
publicfinalclassSomeClass {
// ...
}In python we don't have such feature out of the box.
That's where final_class library comes in!
This package works perfectly with @final from typing.
So, with final_class you will have both type-checking and runtime checks.
pip install final_classfromfinal_classimportfinal@finalclassExample(object): # You won't be able to subclass it!
...
classError(Example): # Raises `TypeError`
