NameError issue:

I have tried rearranging my code and nothing seems to work.

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

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

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

The error you are receiving is: NameError: name 'name' is not defined. You don't have a name variable in your class or inside of the eat method, you do have self.name and self.food.

Megan Amendola . Hey, but we cannot define self.food, as the question asked us to let init to take only 3 arguments and eat only self.

This is not working for me either:

class Panda: species = 'Ailuropoda melanoleuca' food = 'bamboo' name = "Bao Bao" age = 1

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}'

This is the error message I get:

  • Bao Bao eats bamboo
  • Bao Bao eats bamboo. ? + : When I call the eat method, I don't get the correct message. Make sure to use the name attribute that is passed in to the instance.

Got it!

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

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

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

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