class Panda:
species = 'Ailuropoda melanoleuca'
food = 'bamboo'
def __init__(self, name, age):
self.is_hungry = True
self.name = name
self.age = age
def eat(self):
self.is_hungry = False
return f"{self.name} eats{Panda.food}"
My thought was that food is a class attribute, not an instance attribute. Can't I use Panda.food instead of self.food? I would like to know the reason. Thank you!

If you think it's just a bug in the course, you may want to report this to Support. If they agree, it will get you a "special Exterminator badge".
