I really enjoyed this. A very quick introduction to Python and pandas, using a very important dataset, the Coronavirus data. In addition to Python, he also shows how to use PivotTables.js, a very interesting web application like a spreadsheet to group countries by age and sex, just drag and dropping the parameters. I recommend folks read this, the best statistics are those we make ourselves. Python and pandas makes data analysis very simple, if you make a mistake, finding help is easy, just google..
