Using one method's result for another method in the same Class?

Note that you can turn get_area into property using @property decorator.

class Rectangle:
    def __init__(self, width, height):
        self.width = width
        self.height = height


    @property 
    def area(self):
        return self.width * self.height

rect = Rectangle(10, 2)
print(rect.area)
