Python向数据类型添加自定义函数

class MyClass:
    def __init__(self, value):
        self.value = value

    def custom_function(self):
        return f"Custom function called with value: {self.value}"

# 创建一个MyClass实例
my_instance = MyClass(42)

# 调用自定义函数
print(my_instance.custom_function())

class ParentClass:
    def common_method(self):
        return "Parent method"

class ChildClass(ParentClass):
    def common_method(self):
        return "Child method"

child = ChildClass()
print(child.common_method())  # 输出: Child method

class ChildClass(ParentClass):
    def common_method(self):
        super().common_method()  # 调用父类的方法
        return "Child method extended"
