Using one method's result for another method in the same Class? - btownboy - Sep-12-2020
Hey Guys,
I have a question as mentioned in the title. can you use one method's result for another method in the same Class?. I wish to use the result of the area method in the get_amount_inside method. Is there a way to do this? or put the equation for area L*W.
Thanks for your Help!
class Rectangle:
def __init__(self, width, height):
self.width = width
self.height = height
def get_area(self):
area = self.width * self.height
return area
def get_amount_inside(self, shape):
self.shape = shape
if self.shape == "sq":
num_times = self.area/(self.width * self.width)
return num_times

Sure. Normally you'll just use self to call the method. Something like:
def get_amount_inside(self):
area = self.get_area()
# do more stuff using the area....get_area() is a method (function), not an attribute. So you need the parenthesis to call it.

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)
