Code apparently runs properly, but I keep getting the error message: Oops, try again. Did you create an instance of Triangle called my_triangle?
In the preview box, the code prints:
... so I would expect the code to be ok. What am I doing wrong?
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(90, 45, 45) print my_triangle.number_of_sides print my_triangle.check_angles()
