如何在Python中获取类属性的定义顺序？

import inspect

class MyClass:
    def __init__(self):
        self.first_attribute = "first"
        self.second_attribute = "second"
        self.third_attribute = "third"

def get_class_attribute_order(class_obj):
    attributes = []
    for name, obj in inspect.getmembers(class_obj, lambda obj: not inspect.isroutine(obj)):
        if not name.startswith("__") and not name.endswith("__"):
            attributes.append(name)
    return attributes

class_instance = MyClass()
attribute_order = get_class_attribute_order(MyClass)
print(attribute_order)

['first_attribute', 'second_attribute', 'third_attribute']
