Should be able to just use list(vocs) here.

input(v) should do the same job of issuing a prompt.

Strongly recommend using a 'while' loop rather than recursion, even
from the start. Don't teach bad practices and then replace them later.
If you have to, do something like:
while True: # don't worry about what this line does yet
and then explain it later. Better to have a bit of magic that you
later explain than bad code that people will copy and paste.

That's only an issue when you're working interactively, so I wouldn't
worry about it. Either assign to a junk variable ("_ = whatever" is
common) or just let it get printed.
