Final classes for Python 3

Project description

final_class Build Status Coverage Status wemake-python-styleguide

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:

public final class SomeClass {
  // ...

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_class


from final_class import final

class Example(object):  # You won't be able to subclass it!

class Error(Example):  # Raises `TypeError`
