      Pandas is such a unique learning experience. It's the only tool where my mental model changes substantively every time I use it. Yet, I find Pandas hard to "properly" learn because all the tutorials are boring stock market examples.

      There's infinite cases where I can articulate the high-level task, and have no idea how to accomplish it without a for loop & iterrows.

      Like today, I wanted to filter outliers within a group defined by two columns. Found an SO post about doing this within a single-column group. It used a novel mechanism (broadcasting between dataframes of different sizes) and I kept failing to transfer the example to my task.

          Maybe Pandas is just overly complex. I liked @yifanwu's example of 8 different ways to filter a dataframe.pic.twitter.com/J3xLfiVHeG

          But at the same time, for the parts of the programming model that I do understand, I feel really productive. It's like a beautiful mix of SQL and jq. I never have to use a for-loop, and I rarely even need a higher-order function.

          Omg this relates so hard. Because 80% of the time cargo culting stackoverflow works just fine! I don't think anyone knows the answer to this, besides direct peer help and clarification (perhaps GPT-3 :P)

          I think this could help. But I do think it's important to cut out SO where possible -- I want Pandas fluency to the point where I can code at the speed of thought, and going to Google is slow.https://twitter.com/wcrichton/status/1283628245531848704 …

          I think there would be massive value in automatic contextualization of a tutorial. The pandas multi-index doc is hard to parse because it's full of "foo/bar/baz/quux" random data. But if the data were familiar to me, maybe that would be easier?

      Loading seems to be taking a while.
