# print(type(list1))
# # #
# str1 = json.dumps(list1, ensure_ascii=False)
# print(str1)
# print(type(str1))
# # # print(type(str1))
# # #
# a = json.loads(str1)
# print(a)
# print(type(a))
#
# #
# # dict1 = {"信息":{"name": "张三"},"班级":{"class":9}}
# # print(type(dict1))
# # a = json.dumps(dict1, ensure_ascii=False)
# # print(a)
