Serializing Python Objects with Pickle and Shelve

Object serialization and persistence can be incredibly useful if you need to share data between multiple applications or save data for use later. Python provides utilities for serializing and deserializing Python objects to and from bytes, to make it possible to pass Python data structures between Python applications or to read/write to a file without needing to convert to an intermediate data format like JSON. In this hands-on lab, you'll utilize these features in the standard library to create a simple flashcard command line application. By the time you've finished this lab, you should have a good understanding of how to use the `pickle` and/or `shelve` modules from the Python standard library.
