AttributeError: 'Triangle' object has no attribute 'check_angles'


Not sure what's wrong with my code...

class Triangle(object):
    number_of_sides = 3
    def __init__(self, angle1, angle2, angle3):
        self.angle1 = angle1
        self.angle2 = angle2
        self.angle3 = angle3
def check_angles(self):
    if self.angle1 + self.angle2 + self.angle3 == 180:
        return True
        return False
my_triangle = Triangle(60, 60, 60)
print my_triangle.number_of_sides
print my_triangle.check_angles()


Oh, it's a wrong indent of my second function.... got it now.


check_angles should be a method, it should be part of the Triangle class. In your case it is just a function, since it outside the class, try changing the indent so it is inside the class so it becomes a method
