当其中一个类中有额外的操作时，我如何在不同的类中重用相同的方法？

class BaseClass:
    def common_method(self):
        print("This is a common method.")

class DerivedClassA(BaseClass):
    def common_method(self):
        super().common_method()
        print("Additional operation for Class A.")

class DerivedClassB(BaseClass):
    def common_method(self):
        super().common_method()
        print("Additional operation for Class B.")

class CommonMethods:
    def common_method(self):
        print("This is a common method.")

class ClassA:
    def __init__(self):
        self.common = CommonMethods()

    def perform_action(self):
        self.common.common_method()
        print("Additional operation for Class A.")

class ClassB:
    def __init__(self):
        self.common = CommonMethods()

    def perform_action(self):
        self.common.common_method()
        print("Additional operation for Class B.")

from abc import ABC, abstractmethod

class Strategy(ABC):
    @abstractmethod
    def execute(self):
        pass

class ConcreteStrategyA(Strategy):
    def execute(self):
        print("Common method with additional operation for Class A.")

class ConcreteStrategyB(Strategy):
    def execute(self):
        print("Common method with additional operation for Class B.")

class Context:
    def __init__(self, strategy: Strategy):
        self._strategy = strategy

    def execute_strategy(self):
        self._strategy.execute()
