class Rectangle():     def __init__(self, x, y):         self.x = x         self.y = y       def dRec_area(self1, self2):         area = (self1.x * self1.y) + (self2.x * self2.y)         return area       x1 = input("Please insert the width: ") y1 = input("Please insert the length: ") rectangle1 = Rectangle(x1, y1)   x2 = input("Please insert the width: ") y2 = input("Please insert the length: ") rectangle2 = Rectangle(x2, y2)   print(rectangle1.rectangle2.dRec_area())

How to apply the method on two objects?

[anbu23]

1	print(Rectangle.dRec_area(rectangle1,rectangle2))

[gabejohnsonny21]

TypeError: can't multiply sequence by non-int of type 'str'

why does this error appear after I run the program?

---

Thanks for the help

Input entered is of type string. You got that error since you have not converted to integer before you perform arithmetic calculation

1	x1 = int(input("Please insert the width: "))

A class is usually bigger, has more methods and by convention we use self, other for instances and cls for classes.
By convention camel case should not used in methods. (The functions attached to the class, are methods).
Instead of doing the operation in one step, you can split it up.

First step: Get area of both rectangles
Second step: Add the area

A @property attached as decorator to a method of the class, just return the value without calling it.
