AttributeError: Equilateral instance has no attribute 'angle1


#1

I'm getting the same error (it says ""AttributeError: Equilateral instance has no attribute 'angle1'") but I'm writing it according to how @javarockstar48597 said:

class Triangle(object):
    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(60, 60, 60)
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

Can anyone let me know what I'm doing wrong?
