Here I am unable to understand two things:
1.why can't I use angle1.self instead of self.angle1?
2.In line 18 I use this command my_triangle.number_of_sides can I use this my_triangle.number_of_sides()?
I have added my original code below.
could somebody explain both issues?
class Triangle: 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(90,30,60) print my_triangle.number_of_sides print my_triangle.check_angles()
