A tour of the module itertools
summary
The module contains 20 tools and the talk demonstrates roughly 10 of them, claiming many are lazy like range laziness and work on any iterable. Examples include combinations and permutations for flavor pairs and cones, product to replace nested loops and generate test cases, chain/from_iterable to concatenate files without building large lists, islice to take the first 10 items from a product (used for a battleship bot), pairwise to avoid slice copies, count as an ID generator, and zip_longest filling missing values with None.
