I can't figure out how to call the eat method

Create another method called check_if_hungry that also only takes self. Inside of the method, if the is_hungry attribute is True, then call the eat method.

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 {self.food}.'
    def check_if_hungry(self):
        if is_hungry = True:
            return eat



panda_one = Panda('Bao Bao', 10)
panda_one.eat()

Your new error, the SyntaxError, is because = is an assignment operator! In order to compare in an if statement, it has to be == which is a comparison operator. I hope this helps!

Hi Mario,

You can only invoke eat() on the instance of the Panda class, so instead of returning eat. Return self.eat().

def check_if_hungry(self): if is_hungry == True: return eat(self)

panda1 = Panda("Boa Boa", 10)
panda1.eat()

I seem to keep getting the: : You should be checking if the is_hungry attribute is true. Make sure to use self to call the attribute.error

def check_if_hungry(self):

    if is_hungry == True:

        return eat(self)

panda1 = Panda("Boa Boa", 10)

panda1.eat()

whats wrong with my code: AssertionError: Regex didn't match: 'if\sself.is_hungry\s?=?=?\s?[True]*:' not found in 'class Panda:\n species = \'Ailuropoda melanoleuca\'\n food = \'bamboo\'\n\n def init(self):\n self.is_hungry = True\n def init(self, name, age):\n self.name = name\n self.age = age\n def eat(self):\n self.is_hungry = False\n return f"{self.name} eats {self.food}."\n def check_if_hungry(self):\n if is_hungry == True:\n return eat(self)\n\n \npanda1 = Panda("Boa Boa", 10) \npanda1.eat()' : You should be checking if the is_hungry attribute is true. Make sure to use self to call the attribute.
