There is both the Redmonk index (updated biannually, uses data from GitHub and StackOverflow): https://redmonk.com/sogrady/2020/02/28/language-rankings-1-2...

And the PYPL index (updated monthly, uses data from Google Trends, which counts search queries): http://pypl.github.io/PYPL.html

I regard both of these more accurate indicators of popularity than the TIOBE index. (As for PYPL vs. TIOBE, I find that search queries reflect popularity more accurately than search results)
