Here's all the code and examples from the second edition of my book Data Science from Scratch. They require at least Python 3.6.
(If you're looking for the code and examples from the first edition, that's in the
If you want to use the code, you should be able to clone the repo and just do things like
In : from scratch.linear_algebra import dot
In : dot([1, 2, 3], [4, 5, 6]) Out: 32
