Explore how Python pickle files serialize data and why their raw form is challenging to read. Understand methods to debug pickled data by identifying protocol versions using pickletools. This lesson helps you analyze and troubleshoot serialized Python objects effectively.

We'll cover the following...

What does the pickle protocol look like? Let’s jump out of the Python Shell for a moment and take a look at that entry.pickle file we created. To the naked eye, it’s mostly gibberish.
