Question

Hello Everyone,

Can anyone tell me why my program will not run? I am trying to work on abstract base classes... not sure what is going on.

import math

from abc import ABC

from abc import abstractmethod

#TODO: convert this to an ABC

class Shape(ABC):

def __init__(self):

self.name = ""

def display(self):

print("{} - {:.2f}".format(self.name, self.get_area()))

#TODO: Add an abstractmethod here called get_area

@abstractmethod

def get_area(self):

if self.name == "Circle":

get_area()= 3.14 * radius * radius

else:

get_area() = self.length * self.width

#TODO: Create a Circle class here that derives from Shape

class Circle(Shape):

def __init__(self):

super().__init__()

self.name = "Circle"

self.radius = 0.0

get_area()

#TODO: Create a Rectangle class here that derives from Shape

class Rectangle(Shape):

def __init__(self):

super().__init__()

self.name = "Rectangle"

self.length = 0.0

self.width = 0.0

get_area()

def main():

#TODO: Declare your list of shapes here

s = Shape()

c = Circle()

r = Rectangle()

radius = []

length = []

width = []

command = ""

while command != "q":

command = input("Please enter 'c' for circle, 'r' for rectangle or 'q' to quit: ")

if command == "c":

radius = float(input("Enter the radius: "))

#TODO: Declare your Circle here, set its radius, and

# add it to the list

self.name = "Circle"

radius.apphend

return radius

elif command == "r":

length = float(input("Enter the length: "))

width = float(input("Enter the width: "))

#TODO: Declare your Rectangle here, set its length

# and width, and add it to the list

self.name = "Rectangle"

return length, width

length.apphend

width.apphend

# Done entering shapes, now lets print them all out:

s.display()

#TODO: Loop through each shape in the list, and call its display function

for i in Shape():

s.display()

if __name__ == "__main__":

main()

Note:

Is is properly indented?

Please send me the screenshot of an error, or you can do one thing, you can copy paste the error messages in the comment section.

Note:

I tried executing the code, and here's the problem
get_area()= 3.14 * radius * radius

You cannot directly assign the numeric, decimal values to the function which is causing an error.

Follow up this indentation:
