在python中使用有序的dict作为对象字典

from collections import OrderedDict

class MyObject:
    def __init__(self, data):
        self.data = data

    def __repr__(self):
        return str(self.data)

my_dict = OrderedDict([
    ('name', 'John'),
    ('age', 30),
    ('city', 'New York')
])

my_obj = MyObject(my_dict)
print(my_obj)

OrderedDict([('name', 'John'), ('age', 30), ('city', 'New York')])
