Most of "How NOT TOs" comes from my own beginnings with pandas.
In this guide, I first show an example of “How NOT to” and then show a proper “How to” way of working with pandas. The arguments for improvement are concise, more readable code and faster execution.
You get a 6 page PDF with a Jupyter Notebook so that you can run examples on your laptop.
What will you learn:
How NOT to sum the data.
How NOT to filter the data.
How NOT to access values.
How NOT to apply complex functions.
How NOT to group data.
