PYTHON- what TYPE of work do you do? if you don't do Data science or Machine Learning, what separates Python from others?

I'm trying to figure out the "TYPE" of work to pursue with learning/pursuing Python.

is the need/for python stable vs Javascript? I've been concentrating one Vue and React for a while, up I want to narrow down the type of work. From End is mainly styling.. that's ALWAYS CHANGING.

so far, I'm at 5 hours into a course and I like Py. Tkinter or KIVY interests me, but that's limited to desktop?
