Python Basic Object-Oriented Python Welcome to OOP Adding to our Panda

OOP I don't know why it's wrong

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.

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
        return (f'{self.name} eats {Panda.food}.')

I try self.food, but it still does not work. The same error appears: Bummer: AssertionError: Regex didn't match: 'return\sf?\\'?\"?\{[self.name]\}\seats\s\{[self.food]\}.\\'?\"?[.format]\(?[name\s=\s][self.name,]\s?[food\s=\s][self.food]*\)?' not found in "class Panda:\n species = 'Ailuropoda melanoleuca'\n food = 'bamboo'\n\n def init(self, name, age):\n self.is_hungry = True\n self.name = name\n self.age = age\n \n def eat(self):\n self.is_hungry = False\n return (f'{self.name} eats {self.food}.')" : Use string formatting and backets ({}) to add the name and food attributes to your string. Make sure the message has the correct spelling and a period(.)

Sorry about that Marcus. You also need to delete the parenthesis on the return for it to pass.

In your return instead of Panda.food it should be self.food. Self represents the instance of Panda that you are using.

Keep at it Marcus!
