Useful Pandas Snippets

A personal diary of DataFrame munging over the years.

Data Types and Conversion

Convert Series datatype to numeric (will error if column has non-numeric values)
(h/t @makmanalp)

Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.

General rules

Follow standard conventions.
Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible.
Boy scout rule. Leave the campground cleaner than you found it.
Always find root cause. Always look for the root cause of a problem.

My 2Do tasks

This is just contents of my never ending lists of tasks I tagged in 2Do with read, watch and check tags.

All lists are sorted by priority. I hope to bring all these lists closer to 0 when I get time. But until then, perhaps you will find something interesting in them.

Here are the lists I share so far.
