It's a great question. I'd say for myself I've been hesitant to use CPython or PyPy simply because their documentation seems focused on the extremely technical, rather than a person just trying it out for the first time.
I know Python, and I know C. But I'm worried ending up down rabbit holes in PyPy and competitors. I've not been able to find a really solid tutorial or parse the docs very well.
Perhaps it's just me, though. That's always possible. I just see a large barrier to adoption.
When you say CPython, do you mean Cython? I've only recently learned what "Python" really is myself, and it's easy to miss the difference between these two:
