how will I become a programmer?

I would like to become a programmer, but it seams like getting a high school leaving will be harder then it ot to be. I would like to take a course or be trained in python for now or have something under my belt. Would a tutor be a good choice? I’m just not sure how to go about it. At the moment i don’t even have a computer, but books on it. I’m 21 and feeling like the clock is ticking.
