whats wrong with this?


class Triangle():
    def __init__(self, angle1, angle2, angle3):
        self.angle1 = angle1
        self.angle2 = angle2
        self.angle3 = angle3
    
    number_of_sides = 3
    
    def check_angles(self):
        if self.angle1+self.angle2+self.angle3 == 180:
            return True
        else:
            return False
    
my_triangle = Triangle(45, 45, 90)
print my_triangle.number_of_sides
print my_triangle.check_angles()

class Equilateral(Triangle):
    angle = 60
    def __init__(self):
        self.angle = self.angle1
        self.angle = self.angle2
        self.angle = self.angle3

it says: Oops, try again. Failed to instantiate Equilateral, an error was thrown: Equilateral instance has no attribute 'angle1'

The above needs to be written in reverse order, as given in the instructions.

self.angle1 = self.angle
self.angle2 = self.angle
self.angle3 = self.angle
