For readers who wish to explore a more flexible and reusable technique, this appendix provides an example of using a recursive function to process nested dictionaries and lists of arbitrary depth. Recursion is a programming technique in which a function calls itself in order to solve a problem by breaking it into smaller, similar pieces.
