To LilyPond, this is the same as if you’d have written
#'(a b c)
so there’s neither markup nor music in this that could be printed.

It’s not clear what you want to do. What kind of data do you want to
convert into a string, and for what purpose?
You could just write
$(f "'(a b c)")
of course, but I imagine that’s not what you’re after.
Best, Simon
I just want to output the result of the scheme function I'm learning. Don't need anything fancy but I prefer the clear pdf output instead of lilypond output log.
Thank you Simon,
