NameError: the value for 'food' is not defined

The value for 'food' is established as a class attribute. Why does this not carry over into the function?

panda.py 
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):
        name = 'Boa Bao'
        self.is_hungry = False
        return (f'{name} eats {food}.')

Since it's a class attribute and not a local variable, it needs to be prefixed by "self.".

Also, though "Bao Bao" was used as an example of a name, the challenge didn't intend for that to be established as a static string. Your method should use the attribute which was set by the constructor instead.
