Python core 73.3 Calculating volume

Question

class Rectangle:
def __init__(self, width, height):
self.w = width
self.h = height
def vol(self):
# return volume

w = int(input())
h = int(input())

obj = Rectangle(w, h)
#call the function

"""Im not understanding how to calculate the volume, I understand w*h=vol but how do i plug that into the function"""

Answer 1

William Alley ,

you need to print the result:

...
print(obj.vol())

Answer 2

William Alley

#volume
self.w * self.h

#calling function

obj.vol()

Answer 3

Thank you Lothar this Practice module just made me doubt everything ive been learning because i didnt plug the obj.vol() into print()

Answer 4

class Rectangle:
def __init__(self, width, height):
self.w = width
self.h = height
def vol(self):
volume = self.w * self.h
return volume
# return volume

w = int(input())
h = int(input())

obj = Rectangle(w, h)
#call the function
obj.vol()

Answer 5

It didnt work

Answer 6

This works 100%.
class Rectangle:
def __init__(self, width, height):
self.w = width
self.h = height
def vol(self):
# return volume
return width*height

w = int(input())
h = int(input())

obj = Rectangle(w, h)
#call the function
print(w*h)

Answer 7

class Rectangle:
def __init__(self, width, height):
self.w = width
self.h = height
def vol(self):
# return volume
return width*height

w = int(input())
h = int(input())

obj = Rectangle(w, h)
#call the function
print(w*h)

Answer 8

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

def vol(self):
return self.width * self.height

w = int(input())
h = int(input())

volume = Rectangle(w, h)
print(volume.vol())
