> Does the book use any commercial software like xlwings PRO? No, the book uses exclusively software that is open source and free (except for Excel, of course).

This is no longer technically true of Anaconda. They’ve adopted a new licensing approach that prevents employees of companies from using the free edition. Please consider adding alternative install instructions, based on PyPI and pipenv or poetry, to future versions of your book. This would help a ton of data scientists out!

I’m looking forward to reading your book via O’Reilly!

Edit: Here’s an interesting comment on the Reddit discussion from the Anaconda CEO suggesting that Miniconda can still be used with conda forge: “You can download Miniconda, and change your conda config to use conda forge, and the Terms of Service do not apply to that. The ToS only applies to commercial usage of the package repository of packages we build, at repo.anaconda.com; it does not apply to community-built and uploaded packages at anaconda.org.”, https://www.reddit.com/r/Python/comments/iqsk3y/anaconda_is_...
