return a string that says 'Bao Bao eats bamboo.' where 'Bao Bao' is the name attribute and 'bamboo' is the food attribut

Challenge Task 2 of 3 Create a method called eat. It should only take self as an argument. Inside of the method, set the is_hungry attribute to False, since the Panda will no longer be hungry when it eats. Also, return a string that says 'Bao Bao eats bamboo.' where 'Bao Bao' is the name attribute and 'bamboo' is the food attribute. Please help...

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

You should be using the name instance attribute so a name can be passed in for the Panda and returned. Right now you are creating a name variable inside of the eat method and setting it equal to Bao Bao, so if the user wants to name their Panda "Charles", they will have the wrong name returned to them.

You also don't need the () in the return statement. 

def eat(self):
        self.is_hungry = False
        return f'{self.name} eats {self.food}.'

I just ran into the exact same problem. I had to re-attribute name and food their specific values inside the eat function def eat(self): self.is_hungry = False name = 'Bao Bao" food = 'bamboo' return f'{self.name} eats {self.food}.'

When a panda instance is created, a name and age have to be passed, for example:

panda = Panda('Charles', 2)

Inside of dunder init, it takes the name that was passed in and sets it as an instance attribute. Inside of eat, you are accessing the name instance attribute and the class food attribute to return the message. 

return f'{self.name} eats {self.food}.'

So for this instance, it would return 'Charles eats bamboo' when panda.eat() is called.

I could create a different instance panda2 = Panda('Nia', 5) and when I call panda2.eat() I should then get 'Nia eats bamboo'.
