You think? I'll admit that my view of the Python community is super narrow, but I was thinking Django, me writing a bunch of test scripts, backend stuff. I know data science is a "thing" with Python, but I just didn't imagine that it had become it's main use. I guess TIL there's a whole other world of how people use Python, and it might be most of them. :-)
My personal impression is that Python is used in more fields than almost any other language, but that every community is only peripherally aware of other communities.
For example, Python is big in Earth Sciences (or so I am told). Almost nobody outside Earth Sciences knows that.
Until maybe 5 years ago, I had no idea that people used Python for web development. It had just never occurred to me. GvR famously had to google what wsgi was.
So I think your final sentence probably applies to most users of Python.
I can't think of other niches right now, but whatever one you think, it's probably on the top 5 there.
