推荐答案
您可以保存程序的状态(特定对象的).想象一下，您有一个运行数小时甚至数天的程序.使用pickle，您可以保存计算状态，终止程序并在以后继续计算(如果需要).
You can save the state of a programm (of specific objects). Imagine you have a program which runs for many hours or even days. Using pickle you can save the state of the calculation, kill the programm and resume the calculation later if you want to.
您甚至可以通过电子邮件将保存的对象发送给其他人，他们可以继续计算或查看您的结果.
You could even email the saved objects to other people, who than can resume the calculation or view your results.
我有时会挑选用户偏好或(在测验中)上次问的问题以及给出的答案.
I sometimes pickle userpreferences or (in a quiz) what questions where asked the last time and what answers were given.
