I work at a fintech company doing Spring Boot, and the only python I've seen here is in some CI scripts (which I can see but do not have access to edit, we have a team that maintains CI). Everything else is Java, Kotlin, or JS for some websites, that's about it. I've heard the AI teams use python, but while pretty much all the devs in my team know python, we don't use it at all.
Similar here. One exception is that we had some Lambdas written in Python. Now there is a push to replace them with Go because of the potential money savings from faster execution times.
