Python Coding challenge - Day 903| What is the output of the following Python Code?

 

Code Explanation:

1. Class Definition

class Calc:

Explanation:

A class named Calc is created.

It will contain a method that behaves differently depending on the number of arguments passed.

2. Method Definition With Default Values

def process(self, x=None, y=None):

Explanation:

The method process() accepts two optional parameters: x and y.

If no values are passed, they are automatically None.

This allows the method to act like an overloaded function in Python.

3. First Condition: Both x and y Present

if x and y:

    return x * y

Explanation:

This runs only when both x and y have values (not None or 0).

In that case, the method returns the product of the two numbers.

4. Second Condition: Only x Present

elif x:

    return x ** 2

Explanation:

This runs when only x has a value and y is None.

It returns the square of x (x × x).

5. Default Case: No Valid Input

return "Missing"

Explanation:

If neither x nor y is provided (or both are falsy), the method returns "Missing".

6. First Function Call
Calc().process(4)

What happens?

x = 4

y = None

First condition: if x and y → False (because y is None)

Second condition: elif x → True

→ returns 4 ** 2 = 16

7. Second Function Call

Calc().process(4, 3)

What happens?

x = 4

y = 3

First condition: if x and y → True

→ returns 4 * 3 = 12

8. Final Print Output

print(Calc().process(4), Calc().process(4, 3))

Output:

First result → 16

Second result → 12

FINAL OUTPUT

16 12
