All examples and resources in this textbook are written in the Python programming language. Python is an open source (under OSI), interpreted, general-purpose programming language that has a large number of users around the world. It is the top-ranked language in January 2023 by the TIOBE programming community index¹, a measure of popularity of programming languages. A more robust tutorial of the language can be found at https://www.python.org/.

This book uses Replit, an online browser-based IDE for Python and several other languages. Replit may be accessed for free at https://www.replit.com/.

Much of the content in this chapter is from "First Semester in Numerical Analysis with Python", available at https://open.umn.edu/opentextbooks/textbooks/925.
