# Python Coding challenge - Day 198 | What is the output of the following Python Code?

### Code:

def __mul__(self, other):
return super().__mul__(other + 4)
result = q * 3
print(result)

### Solution and Explanation:

let's delve into this code:

class Quadrupler(int):: This line establishes a new class named Quadrupler that inherits from the int class. As a result, Quadrupler inherits all the attributes and methods of the int class.
def __mul__(self, other):: This creates a special method __mul__() which overrides the multiplication behavior of instances of the Quadrupler class. This method is invoked when the * operator is utilized with instances of the Quadrupler class.
return super().__mul__(other + 4): Within the __mul__() method, it adds 4 to the other operand and then invokes the __mul__() method of the superclass (in this case, the int class) using super(). It transfers the adjusted other operand to the superclass method. Essentially, it performs multiplication of the Quadrupler instance with the modified value of other.
q = Quadrupler(5): This line instantiates an object of the Quadrupler class with the value 5. Since the Quadrupler class inherits from int, it can be initialized with an integer value.
result = q * 3: This line utilizes the * operator with the Quadrupler instance q and the integer 3. Since the Quadrupler class has overridden the __mul__() method, the overridden behavior is invoked. In this case, it adds 4 to the other operand (which is 3) and then performs multiplication.
print(result): Lastly, this line prints the value of result.

other is 3.
4 is added to other, making it 7.
The __mul__() method of the int class (the superclass) is invoked with 7 as the argument.
The superclass's __mul__() method multiplies the Quadrupler instance (q) by 7.
The outcome of this multiplication is assigned to result.
Finally, result is printed.
Hence, when you execute this code, it should output 35, which is the result of multiplying 5 by (3 + 4).
