Python序列化与反序列化pickle用法实例

import pickleclass Bird(object):	have_feather = Truereproduction_method = "egg"## 创建一个对象summer = Bird()pickle_string = pickle.dumps(summer)# 已被序列化成二进制数据with open("summer.pkl", "wb") as fp:	fp.write(pickle_string)# dump方法可以把上面两步作为一步来完成：# with open(	"summer.pkl", "wb") as fp: #pickle.dump(	summer, fp)# 从磁盘文件上恢复对象： 先读取文件， 再loadswith open("summer.pkl", "rb") as fp:	summer = fp.read()# 先读取summer = pickle.loads(summer)# 再序列化print(summer.have_feather)# 或者用load方法， 一步到位# with open(		"summer.pkl", "rb") as fp: #summer =	pickle.load(fp)# print(summer.have_feather)
