A class is a blueprint for creating objects. What if we want to create another Panda using that class and that panda will have a different name - like "Mao Mao" for example. Then the eat method would not make sense as it will also say: "Bao Bao eats ...". We want it to be re-usable so that we can create different pandas with different names and when we call the eat method on any one of those, it'll say the correct name - the name we initialized the object with :)

1,637 PointsOk, and where and how should I declare the name Bao Bao?

1,637 PointsThanks for your help! This is the code I wrote for now
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
name = 'Bao Bao'
return (f*"{name} eats {food}.")

7,992 PointsYou don't need to declare the "Bao Bao" name in the eat method. If I understand correctly a new panda object is created under the hood by Treehouse workspace something along the line of this:
panda1 = Panda("Bao Bao", 10)
..and then they use the eat method on this new panda object - like that:
panda1.eat()
The name and age is passed in to the constructor / initializer when panda1 is initialized. This is is why we declare the name and age in the def init(self, name, age) thingie - then we can use these values in the methods (like the eat method).
With the class, we can create as many pandas as we want:
panda1 = Panda("Bao Bao", 10)
panda2 = Panda("Bao Mao", 6)
panda3 = Panda("Mao Mao", 4)
panda4 = Panda("Yao Yao", 3)
And as I mentioned - we can call the eat() method on any one of those, and it'll say the correct name.
But I realize the confusing part is that we don't initialize the object ourselves - we just have to create the blueprint (class), so that the Treehouse machine is able to use that class to initialize pandas and check if we know how to declare a class in Python.
Ps! I hope I did not mess anything up with Python's OOP. If i did, please someone smarter correct me.

1,637 PointsYes I understand your point, but I still can get it right! This is what I´ve done
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*"{name} eats {food}.")
Panda.eat('Bao, Bao')
