python exercises with solutions init method code example

Example: python exercises with solutions init method

>>> class Triangle(object):
...     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
...
>>> class Equilateral(Triangle):
...   angle = 60
...   def __init__(self):
...        self.angle1 = self.angle2 = self.angle3 = self.angle
...
>>> my_triangle=Triangle(90,30,60)
>>>
>>> print my_triangle.number_of_sides
3
>>> print my_triangle.check_angles()
