Python Coding challenge - Day 1027| What is the output of the following Python Code?

 

Code Explanation:

1. Defining the Class

class Mask:

A class named Mask is defined.

2. Defining a Class Attribute

    y = 10

y is a class attribute.

Normally, accessing m.y would return 10.

🔍 3. Overriding __getattribute__

    def __getattribute__(self, name):

__getattribute__ is a special method.

It is called for every attribute access, without exception.

This includes access to:

instance attributes

class attributes

methods

even special attributes

4. Checking the Attribute Name

        if name == "y":

            return 50

If the requested attribute name is "y":

The method immediately returns 50.

Python does not continue normal attribute lookup.

5. Delegating Other Attributes Safely

        return super().__getattribute__(name)

For all attributes except y:

Python calls the original object.__getattribute__.

This avoids infinite recursion.

This ensures normal behavior for other attributes.

6. Creating an Instance
m = Mask()

An object m of class Mask is created.

7. Accessing m.y

print(m.y)

Step-by-step:

Python calls:

Mask.__getattribute__(m, "y")

The condition name == "y" is True.

The method returns 50.

The class attribute y = 10 is never accessed.

8. Final Output
50

✅ Final Answer

✔ Output:

50
