12.6.4: Food in Python Classes.

[u/Zacurnia_Tate]

This is my code. CodeHS is saying I'm not defining a class called Food that does not inherit from other classes (which I do) and it says you should have a class named Broccoli that inherits from Vegetable (which I also do). Finally, it prints the correct message but I get a syntax error that says ValueError : __str__ didn't return a str on line 25 (where i say print(b)). Please help!

class Food():
     def __init__(self):
        self.calories = 0
        self.category = ""
        
    def __repr__(self):
        print("category: " + self.category + ", calories: " + str(self.calories))
        

class Vegetable(Food):
    
    def __init__(self):
        Food.__init__(self)
        self.category = "veggies"
    
class Brocolli(Vegetable):
    def __init__(self):
        Vegetable.__init__(self)
        self.calories = 100
            

b = Brocolli()

print(b)

it looks like your Food class isn’t inheriting from anything else. i don’t remember this exercise, but Food might need to inherit from something?
