Json与pickle数据序列化181031

json序列化

json是Python，Java等语言通用的，但是只能序列化简单的数据类型

# Author:Li Dongfeiimport jsoninfo = { ???"name":"dongfei", ???"age":"24"}f = open("test.txt","w")f.write(json.dumps(info))f.close()

json反序列化

# Author:Li Dongfeiimport jsonf = open("test.txt","r")data = json.loads(f.read())print(data["name"])

pickle序列化

只有Python内部支持pickle

# Author:Li Dongfeiimport pickledef f1(): ???print("hello")info = { ???"name":"dongfei", ???"age":"24", ???"func":f1}f = open("test2.txt","wb")f.write(pickle.dumps(info)) ?# == pickle.dump(info,f)f.close()

pickle反序列化

# Author:Li Dongfeiimport pickledef f1(): ???print("hello")f = open("test2.txt","rb")data = pickle.loads(f.read()) ?# == pickle.load(f)print(data["func"]())

注意：虽然可以dump多次，但是只能load一次，所以只需要dump一次
