Python Coding challenge - Day 902| What is the output of the following Python Code?

 

Code Explanation: 

1. Class Definition

class Test:

Explanation:

A class named Test is created.

It contains a method show() that behaves differently depending on how many arguments are passed.

This is an example of method overloading-like behavior in Python.

2. Method Definition With Default Parameters

def show(self, a=None, b=None):

Explanation:

The method show() takes two optional parameters: a and b.

a=None and b=None mean that unless values are given, they automatically become None.

3. First Condition

if a and b:

    return a + b

Explanation:

This runs when both a and b have truthy (non-zero/non-None) values.

It returns a + b.

4. Second Condition

elif a:

    return a

Explanation:

This runs when only a is truthy.

It returns just a.

5. Default Return

return "No Value"

Explanation:

If neither a nor b are given, the method returns the string "No Value".

6. First Function Call

Test().show(5)

Explanation:

Here, a = 5, b = None

Condition check:

if a and b → False (b is None)

elif a → True

So it returns 5.

7. Second Function Call

Test().show(5, 10)

Explanation:

Here, a = 5, b = 10

Condition check:

if a and b → True

So it returns 5 + 10 = 15.

8. Final Print Statement

print(Test().show(5), Test().show(5, 10))

Explanation:

First call prints 5

Second call prints 15

Final Output

5 15
