Lazy recursion, with generators

This article explores the use of Python generators to improve memory usage in recursive code.

The author demonstrates how to implement a recursive function to print paths in a file structure using generators to avoid eager evaluation and potential memory issues. The generator-based solution is more flexible and can handle use cases such as printing and storing paths in a list.

The author introduces the `yield from` statement to simplify the code further. They recommend checking out James Powell's in-depth talk on generators for more information.
