Python 獲取json數據中的key和value

import json
先導入需要的庫

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

# 將json字符串轉換成dic字典對象

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