My pandas canonicals ⬅ please critique!

When asking a question here, please describe the problem you are trying to solve, rather than asking about the method you think is the solution to that problem. This is known as the XY problem and can easily be averted if you ask the right questions. This will make it easy for us to understand what you're trying to do, and help you arrive at the best solution for your problem even sooner.
