code for Data Science From Scratch book
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
and so on and so forth.
In order to use the library like this, you need to be in the root directory (that is, the directory that contains the
scratchfolder). If you are in the
scratchdirectory itself, the imports won't work.
It's possible that it will just work. It's also possible that you may need to add the root directory to your
PYTHONPATH, if you are on Linux or OSX this is as simple as
(substituting in the real path, of course).
If you are on Windows, it's potentially more complicated.
