one can argue about how much of an exact science Tiobe or other indices are but Python definitely is everywhere and has continued to grow in a lot of domains. And I think deservedly so because to me it is by far the most pleasant and versatile general purpose language around. People have their legitimate gripes about performance but a language that is used for everything from scripting to gigantic industy scale applications (largest I'm aware of is a ~30 million LOC codebase at JPMorgan) has done some things right.
30MKLOC in Python? Largest I've seen is 500K and that was one overcooked codebase. So problematic. They were looking at a Java rewrite. I'd love to read a lengthy insider exposé on that JPM codebase.
