字符串序列化是将对象状态写入字节流的过程.在python中，"pickle"库用于启用序列化.该模块包含一个强大的算法，用于序列化和反序列化Python对象结构. "Pickling"是将Python对象层次结构转换为字节流的过程，"unpickling"是相反的过程.
pickle模块的演示如下 :
import pickle
#Here's an example dict
grades = { 'Alice': 89, 'Bob': 72, 'Charles': 87 }
#Use dumps to convert the object to a serialized string
serial_grades = pickle.dumps( grades )
print(serial_grades)
#Use loads to de-serialize an object
received_grades = pickle.loads( serial_grades )
print(received_grades)上述程序生成以下输出 :
