How to Write a Data Structure to Disk in Python

A lot of the data structures are graph like and is always in this sort of impu because you can model a graph in Python in memory but then how do you write that to disk now? So I don't know if we did it in the most elegant way possible. That's not the one. But yeah basically we've got a table called content item and then we've got another table for marking like what is what which content item is a prerequisite of which other content item. And so from those two tables, we generate a curriculum object as wellthat says like do these content items in a specific order then from that we generate a can band board for a learner.
