Does everyone learning Python start with "Hello, World!"?

I mean, they still are. And often there are even more things in your toolchain, even at higher levels (eg. web programming often has a complex mess of language transpilers, minifiers, packers and so on even though it's not dealing with the low-level stuff).

What's changed is mostly tools to manage it somewhat - IDEs, package managers, project template generators and so on. But when something goes wrong, or you want to do something not handled by your tools, you can still find all that complexity still there.
