+1 Seconding this. My limited experience with pandas had a non-trivial number of moments "?? Is it really like this? Nah - I'm mistaken for sure, this can not be, no one would do something insane like that". And yet and yet... Fwiw since I've found that numpy is a must (ofc), but pandas is mostly optional. So I stick to numpy for my writing, and keep pandas read only. (just execute someone else's)
