Python 词典(Dict) 加载与保存示例

Dict的加载：

import jsondef load_dict(filename): '''load dict from json file''' with open(filename,"r") as json_file:  dic = json.load(json_file) return dic

Dict的保存：

import jsonimport datetimeimport numpy as npclass JsonEncoder(json.JSONEncoder): def default(self, obj):  if isinstance(obj, np.integer):   return int(obj)  elif isinstance(obj, np.floating):   return float(obj)  elif isinstance(obj, np.ndarray):   return obj.tolist()  elif isinstance(obj, datetime):            return obj.__str__()  else:   return super(MyEncoder, self).default(obj)def save_dict(filename, dic): '''save dict into json file''' with open(filename,'w') as json_file:  json.dump(dic, json_file, ensure_ascii=False, cls=JsonEncoder)
