The problem is that's not really how people get started. Hello world is how you get started in a university intro course, not in your parents' basement.
What happens there is that you have a pile of photos that are all in one folder and you want to organize them into separate folders by date. A problem you're actually having, not a homework assignment. Which is possible to do automatically, because they all have metadata with that information in it. So you find a python script somebody wrote to do that, and it works! Then you realize the script is just a text file and you can modify it to sort using geotags or something else instead, and now you're down the rabbit hole. But only if it's easy to see and modify the code that runs on the device you actually use.
Not everyone learns the same way or for the same reasons.
For example, I learned to read at the same time I learn to code, and from the same source — I had the unusual combination of not just the right birth year, but well-off parents and two elder siblings that had gotten bored of their Commodore 64 just as I was reaching reading age.
Back then my coding was, naturally, 95% transcribing from the manual, but it was fun. One of the few ones I can remember reasonably well this far removed from the experience was a sentence generator that had a list of nouns, verbs, etc and picked from them to build grammatically correct gibberish.
Hello world is how a lot of us started in C with the K&R book, wherever we were. Most of us didn't want to organize photo folders, we wanted to make the computer display something cool or play a song or something, and usually we had to start with something elementary when tackling a new language, especially a complicated one like C.
I can still remember being 11 years old and meticulously keying in the hello world program on my dad's aging Tandy Model 16, then saying 'cc hello.c' and watching as the compiler chugged through the tiny program for a minute or two. (It #includes stdio.h, so there was more code to go through than it seemed, plus there was a linking step. And not much actually happened, because Unix C compilers are silent if there are no errors.)
When I ran a.out and saw "hello world" appear, I was over the moon. It was like clearing 1-1 in Super Mario Bros. for the first time. Like I had surmounted the first obstacle and was thus ready for all the challenges that lay ahead.
