I keep getting name error

It keeps saying that ‘name’ is not defined, but I have no idea how to define it as “Bao Bao”. It won’t work if I put the name “Bao Bao” in the string, so what am I doing wrong?

panda.py
class Panda:
    species = 'Ailuropoda melanoleuca'
    food = 'bamboo'

    def __init__(self, name, age):
        self.name = name
        self.age = age
        self.is_hungry = True

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

You're very close!

We'll need to move the is_hungry = False line up and above the return line though. As it will be unreachable code if it's below. Once something is returned, that function will stop running and code below it will not be ran.

You're already setting the name property perfectly in your __init__ method, "Bao Bao" is just what the back end testing will send when it attempts to create a new Panda. To access the name and food properties in that return line though, we'll need to use self. 👍

class Panda:
    species = 'Ailuropoda melanoleuca'
    food = 'bamboo'

    def __init__(self, name, age):
        self.name = name
        self.age = age
        self.is_hungry = True

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

Most of Travis' suggestions are good, but the "eat" method doesn't need to test anything. It should always do the same thing when called.

In the next step, you will construct another method that will use a conditional.
