It is a way to convert a python object (list, dict, etc.) The pickle library in Python allows you to write and read objects into binary files. into a character stream. Serialization is a more primitive notion than persistence; although pickle reads and writes file objects, it does not handle the issue of naming persistent objects, nor the (even more complicated) issue of concurrent access to persistent objects. Python's standard library uses it for multi-processing.
