How to get all members of a class in python in order?

I'm trying to get all the members of a class, but in order... Here's a MWE

class example:
    def __init__(self):
        self.c = 3
        self.z = 5
        self.a = 5
        self.b = 3
ex = example()
members = [attr for attr in dir(ex) if not \
                   callable(getattr(ex, attr)) and not attr.startswith("__")]

print(members)

This prints: ['a', 'b', 'c', 'z']

For the life of me, I can't figure out why its alphabetizing things. Ideally, I want it as ['c','z','a','b']

You could use the __dict__ attribute:

>>> class example:
        def __init__(self):
            self.c = 3
            self.z = 5
            self.a = 5
            self.b = 3

>>> example().__dict__
{'c': 3, 'z': 5, 'a': 5, 'b': 3}
>>> list(example().__dict__)
['c', 'z', 'a', 'b']
