Learn Interfaces by Building an Equation Solver - Step 17

Hey everyone!
I’m stuck on this step. My code returns the correct coefficients for each degree and does it in the most efficient way I can think of, but it won’t accept it! Am I missing something?
Thanks in advance!

Your code so far

from abc import ABC, abstractmethod

class Equation(ABC):
    degree: int
    
    def __init__(self, *args):
        if (self.degree + 1) != len(args):
            raise TypeError(
                f"'Equation' object takes {self.degree + 1} positional arguments but {len(args)} were given"
            )
        if any(not isinstance(arg, (int, float)) for arg in args):
            raise TypeError("Coefficients must be of type 'int' or 'float'")
        if args[0] == 0:
            raise ValueError("Highest degree coefficient must be different from zero")

# User Editable Region

        coefficients = {(self.degree-key): val for (key, val) in enumerate(args)}
        print(coefficients)

# User Editable Region

    def __init_subclass__(cls):
        if not hasattr(cls, "degree"):
            raise AttributeError(
                f"Cannot create '{cls.__name__}' class: missing required attribute 'degree'"
            )
    
    @abstractmethod
    def solve(self):
        pass
        
    @abstractmethod
    def analyze(self):
        pass
        
class LinearEquation(Equation):
    degree = 1
    
    def solve(self):
        pass
    
    def analyze(self):
        pass

    
lin_eq = LinearEquation(2, 4)

are you adding a new attribute to the class tho?

Omg that was it. I just needed to change it to “self.coefficients”.
Stupid oversight, thank you for pointing it out lol
