Harvard recently dropped PHP to add in Python. Is this a hint to a growing demand in Python programming? More importantly, is this a hint that more applications will run on Python? My understanding is that it's used in a lot of open-source projects and by a lot of tech startups. Right now I have a couple languages under my belt (most for front-end dev) but I do plan on getting into the security sector years from now. I've been studying JS pretty hardcore for the path 4-5 months and was planning on learning some backend/database languages afterward but should I pause that to learn Python?
