如何调用作为属性选通的python函数？

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

    def instance_method(self):
        return f"Instance method called with value: {self.value}"

    @staticmethod
    def static_method():
        return "Static method called"

    @classmethod
    def class_method(cls):
        return f"Class method called from class: {cls.__name__}"

# 创建类的实例
obj = MyClass(10)

# 调用实例方法
print(obj.instance_method())  # 输出: Instance method called with value: 10

# 调用静态方法
print(MyClass.static_method())  # 输出: Static method called
print(obj.static_method())      # 输出: Static method called

# 调用类方法
print(MyClass.class_method())   # 输出: Class method called from class: MyClass
print(obj.class_method())       # 输出: Class method called from class: MyClass
