How the pickle in Python uses __python

Pickle to serialize/deserialize an object, you can persist an object for storage.

For example, you have an object, want to run the program the next time direct use, you can directly use pickle package to save to the hard disk. Or you want to pass an object to another program on the network, you can package it with pickle, then pass it over, and the Python program over there can be used with pickle deserialization.

in usage, it has two functions: load and dump,load are extracted from the serialized data, and dump is the object serialization. Just look at the help, it's simple.
