Trouble with methods challenge. Help please

Not sure what I'm doing wrong here. First I had a print function where the return function now is and... it didn't like it. Please help.

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

Hi matthew mahoney, you are really close. Two errors to fix:

  • the checker is looking for a space following the keyword return.
  • the references to instance attributes need to include “self”: self.name and self.food

The parens within a return statement may still be valid to group the return value across multiple lines. Python forgives the absence of space before the open paren, but the checker and PEP8 are against it.

Post back if you need more help. Good luck!!!

So return is a keyword and not a function. Also return does not send anything to the standard out. If you want that value printed you would need to do something like: 

sad_panda = Panda('sad', 1)
result = sad_panda.eat()
print(result)

# or

print(sad_panda.eat())

Also you probably should not have name in the body of the class and the __init__ method.

I hope this helps.
