I was doing my code and kept getting an error message, an I've since figured out the error but can't seem to understand why it is an error.
My first code was this:
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, angle1, angle2, angle3): if self.angle1+self.angle2+self.angle3 == 180: return True else: return False my_triangle = Triangle(90,30,60) print my_triangle.number_of_sides print my_triangle.check_angles()
However, after seeing various codes and posts, I've since realised that I have to remove the arguments angle1, angle 2 and angle 3 from the check_angles() function. I've tried that and sucessfully completed the exercise.
I haven't understood it though.
Why do I have to remove those 3 arguments? Don't I also need to put them in since they're going to be used?Can anybody explain it to me?
Thank you so much!
