我的调用 check_angles 返回以下内容而不是 True:
<bound method Triangle.check_angles of <Triangle object at 0x7fb209a66b50>>
这是代码:
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():
if angle1 + angle2 + angle3 == 180:
return True
else:
return False
my_triangle = Triangle(60, 60, 60)
(print my_triangle.number_of_sides)
(print my_triangle.check_angles)
