I took an HTML elective in high school, and I think a Flash elective as well (might’ve been the same class, it’s a long time ago). And I took one python class in university, but that was all basic python (v1 or v2, can’t remember, I just know it for sure wasn’t v3).
Other than that, I’m self taught on everything I host/do. My professional field is emergency response (I’ve bounced around every specialty except security/policing) so very little IT exposure in my day to day work life.
