python itertools

The key to iteration in Python A key feature of Python is it's incredible support for lazy iteration. Defining and consuming lazy sequences in Python are easy. You can even define an infinite sequence like powers of 2 or prime numbers! To make working with iterables in Python even easier, Python provides some basic building blocks to help you compose iteration primitives in different ways, which is what the itertools module is for. This module comes with 21 different primitives (and many more recipes for how to combine them), which we go over in this video. Will you use them? ― mCoding with James Murphy (https://mcoding.io) Docs: https://docs.python.org/3/library/itertools.html Source code: https://github.com/mCodingLLC/VideosSampleCode SUPPORT ME ⭐ --------------------------------------------------- Sign up on Patreon to get your donor role and early access to videos! https://patreon.com/mCoding Feeling generous but don't have a Patreon?
