Jupyter notebooks for IBM/Cognitive Class's Applied Data Science with Python. Sorted by class and by topic within that class.
Starts very basic, and not a lot of original code on my end: mostly on GitHub because every single one of the notebooks implores you to post it to GitHub, and I figure I might as well indulge them. Plus, having it handy as a reference might be nice.
If you don't know what a notebook is, they're pretty neat; you can download the Jupyter Notebook App to run them. If you don't want to download or maintain anything, you can use something like CoCalc to run them in browser.
They'll show up all pretty here, but with my last run-order and not interactive. You can look at the raw if you want the text itself, which is a JSON file.
