I am creating a class that has abstract methods and overriding in sub classes.

from abc import abstractmethod, ABC


class MethodInterceptor(object):

    @abstractmethod
    def before_execute(self):
        pass

    @abstractmethod
    def after_execute(self):
        pass

    def __getattribute__(self, name):
        attr = object.__getattribute__(self, name)
        if hasattr(attr, '__call__'):
            def new_func(*args, **kwargs):
                self.before_execute()

                result = attr(*args, **kwargs)
                self.after_execute()
                return result

            return new_func
        else:
            return attr

Creating sub class:

class LoggerInterceptor(MethodInterceptor):
    # overriding abstract method
    def before_execute(self):
        print("before")

    def after_execute(self):
        print("after")

Worker class:

class Worker(LoggerInterceptor):
    def __init__(self):
        self.name = "worker"

    def work(self):
        print(f"hi I am {self.name}")


c = Worker()
c.work()

But I am getting an error:
