# json.dumps(info)#将字典转为字符串(序列化)
# json.dump(info,f)#=f.write(json.dumps(info))
# json.load(f))#=json.loads(f.read())

# json.loads((json.dumps(info)))#将字符串转为字典
#Json主要用于不通语言之间的数据交互，支持字典、列表、字符串、元组、集合
# p=pickle.dumps(info1)#将字典转为二进制
# pickle.dump(info1,f)
#一个文件只能dump一次，load一次
# print(pickle.loads(p))#将二进制转为字典
