We originally had you on the talk about the work that you're doing at practical business Python. Looking at the page now your last article pandas group by warning on the 26th which as a recording two days ago looks like you're still really active on practical businessPython. It's been a while to be honest. I spent a lot of time working on the course that we'll talk about in a moment. And so some of this stuff fell by the wayside, but I am getting back into it.
