Starting With Recursion in Python

If you’re familiar with functions in Python, then you know that it’s quite common for one function to call another. In Python, it’s also possible for a function to call itself! A function that calls itself is said to be recursive, and the technique of employing a recursive function is called recursion.

It may seem peculiar for a function to call itself, but many types of programming problems are best expressed recursively.
