Instantiate an Object- my_triangle isn't an instance of the Triangle class


#1

Trying to solve Instantiate an Object: (https://www.codecademy.com/en/courses/python-intermediate-en-WL8e4/3/3?curriculum_id=4f89dab3d788890003000096#).

I'm getting the error message:
'Traceback (most recent call last):
File "python", line 1, in
File "python", line 13, in Triangle
TypeError: object.new() takes no parameters.'

How do I fix this? init takes 3 angles as arguments, but it doesn't seem to recognise them.

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
        else:
            return False

my_triangle = Triangle(30, 70, 80)
print my_triangle.number_of_sides
print my_triangle.check_angles()

Hi thsi line

def ___init___(self, angle1, angle2, angle3):

teh init shoudl be with 2 _ before and after the init

def __init__
