Tell us what’s happening:
I did read and follow all the instructions, and the code does not pass.
Your code so far
from abc import ABC, abstractmethod
# User Editable Region
class Equation(ABC):
degree: int
def __init__(self, *args):
if (self.degree + 1) != len(args):
raise TypeError(
f"'{self.__class__.__name__}' object takes {self.degree + 1} positional arguments but {len(args)} were given"
for arg in args:
if any(not isinstance(arg, (int, float)):
raise TypeError("Coefficients must be of type 'int' or 'float'")
# User Editable Region
def __init_subclass__(cls):
if not hasattr(cls, "degree"):
raise AttributeError(
f"Cannot create '{cls.__name__}' class: missing required attribute 'degree'"
)
