What are you uncertain about, assert or isinstance? Such
statements are frequently used to make sure the function
arguments are of the right type.

So did your code print the string 10 times? When asking for help,
it's useful to show what you tried, and what was expected, and
what actually resulted.
You use * to replicate the string, but that wasn't what the
assignment asked for. So take out the *n part. You're supposed to
use iteration, specifically the while loop.
Your while loop doesn't quit after 10 times, it keeps going. Can
you figure out why?
