如何输出python中类的方法的返回值？

class Triangle: 

     def __init__(self,width,height):
         self.width = width
         self.height = height
        
     def getArea(self):
         area = self.width * self.height / 2.0
         return area
#定义正方形类

class Square:  

     def __init__(self,size):
         self.size = size
     def getArea(self):
         area = self.size  *  self.size
         return area

 

myTriangle = Triangle(4,5)

#输出实例myTriangle的宽、高
print myTriangle.width
print myTriangle.height
