Python:如何获得对象属性的"未排序"列表？

class Example:
    def __init__(self):
        self.attribute1 = "value1"
        self.attribute2 = "value2"

example = Example()
attributes = dir(example)
print(attributes)

['__class__', '__delattr__', '__dict__', '__dir__', '__doc__', '__eq__', '__format__', '__ge__', '__getattribute__', '__gt__', '__hash__', '__init__', '__init_subclass__', '__le__', '__lt__', '__module__', '__ne__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__', '__weakref__', 'attribute1', 'attribute2']

class Example:
    def __init__(self):
        self.attribute1 = "value1"
        self.attribute2 = "value2"

example = Example()
attributes = vars(example)
print(attributes)

{'attribute1': 'value1', 'attribute2': 'value2'}
