9,165 PointsOdd error with return "{} eats {}.".format(self.name, Panda.food), where Panda is apparently not defined.
When I run this code in workspace it runs well without any errors.
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 "{} eats {}.".format(self.name, Panda.food)

9,165 PointsAah, you're right. Apparently it still works when referred to the class by name from inside the class code, but I guess it's just bad practise and should be avoided. Thank you! :)
