将基类转换为派生类python(或更多pythonic方式的扩展类)

class BaseClass:
    def __init__(self, name):
        self.name = name

    def greet(self):
        print("Hello, " + self.name)

class DerivedClass(BaseClass):
    def __init__(self, name, age):
        super().__init__(name)
        self.age = age

    def introduce(self):
        print("I am " + self.name + " and I am " + str(self.age) + " years old.")

# 创建派生类对象
obj = DerivedClass("Alice", 25)
obj.greet()     # 调用基类方法
obj.introduce() # 调用派生类方法

class BaseClass:
    def greet(self):
        print("Hello, I am the base class.")

class DerivedClass(BaseClass):
    def greet(self):
        print("Hello, I am the derived class.")

# 创建基类对象
base_obj = BaseClass()
base_obj.greet()    # 调用基类方法

# 创建派生类对象
derived_obj = DerivedClass()
derived_obj.greet() # 调用派生类方法
