Does "\a" and "\v" have any use?

Question

I was randomly testing in python with strings, trying every single possible combination with "\" i found some interesting ones like \f, try it, but those two.... i didnt understand them

Answer 1

\a (alarm(?)) will make a 'bleep' sound in windows which is pretty fun when i accidentally discover it

\v (Vertical Tab) its probably useless in console though, i'm not sure if its still useable at this point
