Python Itertools for Efficient Combinatorics

# Introduction

Itertools is a powerful Python module that provides a set of fast, memory-efficient, and flexible tools for working with iterators. These tools are handy for solving a variety of combinatorial problems and can save you time and effort when dealing with large data sets. In this tutorial, we'll explore some key functions of the Itertools module and provide examples to help you understand their use.

## Getting Started with Itertools

To begin, you'll need to import the Itertools module. It's included in the Python Standard Library, so you don't need to install any additional packages.
