python 讀寫json

1. 將python dict 寫入json檔案

   • json.dump()

   •   import json  dict = {‘a‘:1213,‘b‘:[‘ad‘,3,‘23fs‘]}       with open("file_path", "w") as json_f:      json.dump(dict, json_f)

2. 讀取json檔案
   • json.load()

   •   import json()  with open("file_path", "r") as json_f:      dict = json.load(json_f)

3. 將python字典轉換成json字串
   • json.dumps()

   •   import json  dict = {‘a‘:1213,‘b‘:[‘ad‘,3,‘23fs‘]}   dict_str = json.dumps(dict)

4. 將json字串轉換成python字典
   • json.loads()

   •   import json  dict_str = ‘{‘a‘:1213,‘b‘:[‘ad‘,3,‘23fs‘]}‘   dict = json.loads(dict_str)
