Thinking Recursively in Python

Last updated 2 years ago by Abhirag Awasthi


Problems (in life and also in computer science) can often seem big and scary. But if we keep chipping away at them, more often than not we can break them down into smaller chunks trivial enough to solve. This is the essence of thinking recursively, and my aim in this article is to provide you, my dear reader, with the conceptual tools necessary to approach problems from this recursive point of view.

Together, we’ll learn how to work with recursion in our Python programs by mastering concepts such as recursive functions and recursive data structures. We’ll also talk about maintaining state during recursion and avoiding recomputation by caching results. This is going to be a lot of fun. Onwards and upwards!
