Creating an instance - can't find my mistake


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
            return False
    my_triangle = Triangle(90, 45, 45)
    print my_triangle.number_of_sides
    print my_triangle.check_angles()


the instance should be created outside of the class. (hint: indention)


Never mind! It was an indentation error.
