Python OOPS Challenge | Day 6 |What is the output of following Python code?

In this code, we define a class Rectangle with an initializer method __init__ and a method calcPerimeter to calculate the perimeter of the rectangle.

Code Breakdown:

1. __init__ method: This is the constructor of the class. When an object of the Rectangle class is created, it initializes the attributes a and b with the values provided as arguments.

def __init__(self, aVal, bVal):

    self.a = aVal

    self.b = bVal

Here, self.a and self.b are set to aVal and bVal, respectively.

2. calcPerimeter method: This method calculates the perimeter of the rectangle using the formula .

def calcPerimeter(self):

    return 2 * self.a + 2 * self.b

3. Creating an object and calling calcPerimeter:

obj = Rectangle(1, 5)

print(obj.calcPerimeter())

Here, we create an object obj of the Rectangle class with a = 1 and b = 5.

Then, calcPerimeter is called on obj, which calculates .

Output:

The output of this code is 12.
