What is the output of calling n2.calculate()?

class Addition:
def __init__(self, f, s):
self.first = f
self.second = s

def calculate(self):
self.answer = self.first + self.second
print("Addition of two numbers = " + str(self.answer))

n1 = Addition(1000, 2000)
n2 = Addition(3000,1000)
n3 = Addition(2000, 4000)
n4 = Addition(3000,4000)

To determine the output of calling n2.calculate(), we will look at the attributes of the n2 instance of the Addition class.

The n2 object is created with the following parameters:

n2 = Addition(3000, 1000)

In the __init__ method, these values are assigned to self.first and self.second. Therefore:

  • self.first = 3000
  • self.second = 1000

When the calculate method is called on n2, it performs the following steps:

  1. It calculates the sum of self.first and self.second:

    self.answer = self.first + self.second
    

    This means:

    self.answer = 3000 + 1000 = 4000
    
  2. It then prints the result:

    print("Addition of two numbers = " + str(self.answer))
    

    This will output:

    Addition of two numbers = 4000
    

Thus, the output of calling n2.calculate() will be:

Addition of two numbers = 4000
