Python20 Introduction to Classes -17


in Python Introduction to Classes -17, I am stuck...
It says an error message like below.
"Oops, try again. Did you create an instance of Triangle called my_triangle?"

I can't figure out why...
This is the code I wrote below.

class Triangle(object):
    number_of_sides = 3
    def __int__(self, angle1, angle2, angle3):
        self.angle1 = angle1
        self.angle2 = angle2
        self.angle3 = angle3
    def check_angle(self):
        if self.angle1 + self.angle2 + self.angle3 == 180:
            return True
            return False
my_triangle = Triangle(90,30,60)
print my_triangle.number_of_sides
print my_triangle.check_angles()

Please give me some advice
Thank you.


Sorry, it was my silly misspelling..
int ---> init...
