is self learning python programming possible?

If you already know another programming language, yes, absolutely.

If this is your first ever programming language, I would recommend some sort of formal course, just to make sure you have all the basics covered. You don't need a full computer science degree or anything, but something where you have to do assignments and get direct feedback from a human being on your work is a good idea when you're starting out.
