Python 获取json数据中的key和value

import json
先导入需要的库

data :  {"identity":" ","cust_name":" ","listtype":" ","start_date":"2019-12-12","end_date":"2019-12-29"}

# 将json字符串转换成dic字典对象

dict_json = json.loads(data)
        for key in  dict_json :
           print ('======key========:'+key+"************value******"+dict_json[key])
