How to solve the identification error

Question

class Shape:
w = int(input())
h = int(input())
def __init__(self, w, h):
self.width = w
self.height = h

def area(self):
print(self.width*self.height)

class Rectangle(Shape):
def perimeter(self):
return 2*(width+height)

r = Rectangle(w, h)
r.area()
r.perimeter()

Answer 1

Amala Yakin ,

it is an *IndentationError*, which means the indent of code lines is not properly done.

> the 2 lines with *input()* should be outside the class

> class rectangle, line with return: ... 2 x self. ... is missing

> please use a proper indent of 4 spaces as suggested in the python pep-0008 *style guide for python code*

> the code also uses a mix of spaces and tabs as indentation that causes errors

Answer 2

Also note that getting input is needed to be done for instanciating the object.
In the rectangle's perimeter function, you need tor every to the object properties via "self"
