如何使用腌汁来保存笛子？ [英] How can I use pickle to save a dict?

问题描述

我查看了 Python文档给出的信息，但是我还是有点困惑。有人可以发布示例代码，写一个新文件，然后使用pickle将字典转储到其中？

I have looked through the information that the Python docs give, but I'm still a little confused. Could somebody post sample code that would write a new file then use pickle to dump a dictionary into it?

推荐答案

尝试这样： / p>

Try this:

import pickle

a = {'hello': 'world'}

with open('filename.pickle', 'wb') as handle:
    pickle.dump(a, handle, protocol=pickle.HIGHEST_PROTOCOL)

with open('filename.pickle', 'rb') as handle:
    b = pickle.load(handle)

print a == b
