Must be doing it much more and much better than you do.
I've started my familiarity with Python after Peter Norvig promised that Python can be an OK substitute to Common Lisp. That promise turned out to be a bold-faced lie, but learning some Python made me more employable, so, I'm not complaining. I've made my first steps using Python when Twisted was popular, there were "old-style" and "new-style" classes and you could raise whatever you wanted (not necessary an exception), setup.py files were written in such a way as to use distutil if setuptools wasn't installed.
I've also contributed to CPython (reported bugs mostly). Wrote a bunch of C, some C++, Rust and Go code that produces Python modules as well as contributed to pip, setuptools, conda... Again, mostly bug reports or small patches for specific bugs, but still.
At day job, my role is in infrastructure, which is mostly written in Python, so, I deal with stuff like Linux kernel to userspace interface, various system utilities, or cloud-related stuff, mostly OpenStack. Another aspect I'm involved with at day job is CI and packaging. Perhaps the utility I wrote that's seen the most use is one that deals with combining multiple wheels into a single wheel to speed up deployment. It's not sophisticated, but turned out to be very useful. Another popular utility is used to dismantle Linux storage so that it can be re-defined and re-assembled. What it does is it traverses /sys/block looking for various devices and connections between them, finds the right order in which these devices need to be stopped / removed / disassembled and does that. Again, this isn't very exciting, but turned out to be useful.
