dic = dict()
dic['a'] = 1
dic['b'] = 2
dic['c'] = 3
print(dic.items())

import json
jsons = json.dumps(dic)
print(jsons)

結果：

dic is: dict_items([('c', 3), ('b', 2), ('a', 1)])
jsons: {"c": 3, "b": 2, "a": 1}

通過使用collecions,進行排序。collections是一個python的內建模組。

import collections
dic = collections.OrderedDict()
# dic = dict()
 
dic['a'] = 1
dic['b'] = 2
dic['c'] = 3
print("dic is:",dic.items())

import json
jsons = json.dumps(dic)
print("jsons:",jsons)

dic is: odict_items([('a', 1), ('b', 2), ('c', 3)])
jsons: {"a": 1, "b": 2, "c": 3}
