Looping while true
A while loop keeps running as long as a condition remains True. You must make sure the condition eventually becomes False, or your loop will run forever (an infinite loop).
How it reads
while stars > 0: checks the condition before each turn
stars = stars - 1 decreases the counter so the loop eventually stops
Cloud tip: Always modify the variable in your condition inside the loop body, otherwise you will get stuck in an infinite loop.
