The home page for An Introduction to Python Programming for Scientists and Engineers, by Johnny Wei-Bing Lin, Hannah Aizenman, Erin Manette Cartas Espinel, Kim Gunnerson, and Joanne Liu (Cambridge University Press, 2022), is located on the publisher's site. The publisher's companion site, with Jupyter notebooks, additional content, etc., is here. The purpose of this site is to provide miscellaneous content and resources that do not fit on the two main sites. This includes links to discount fliers (to make it easier for them to be shared) and teaching programming-related content that is posted on the book's Twitter account.
If you have any questions, comments, errata reports, etc., please email us at: ipyses at johnny-lin.com. The Twitter account for the book is @Lin_etal_IPySEs.
