After about a decade, Python2 finally went end-of-life in 2020.
However, a year after that I was working at a pretty large and well-known company that was still in the process of porting existing Py2 code over to 3.
Being familiar with the way that working code tends to stick around until something hard-breaks it, I was wondering how many people still encounter mission-critical Python2 on a daily basis. I know that the PyPy project has committed to continuing support for 2.7, so I wouldn't be surprised if there's still a lot of Python2 out in the wild.
