Got the code working before but I accidentally exited the tab. I’ve tried using Ai to help me understand reasons why I am failing, but it seems to be rewriting my code instead of helping me understand why my bad code isn’t working.

when you ask for help it’s really helpful if you share the link to the challenge

in this case, here it is: https://www.freecodecamp.org/learn/python-v9/lab-discount-calculator/build-a-discount-calculator

Alright, first failed test:

When apply_discount is called with a price (first argument) that is not a number (int or float ) it should return The price should be a number .

what is your function returning in this case?
test it

print("actual:    ", apply_discount("", 97))
print("expected:  ", "The price should be a number")

what is it returning?
