Python Coding challenge - Day 1134| What is the output of the following Python Code?

 

Code Explanation:

🔹 1. Class Definition

class Test:

✅ Explanation:

A class Test is created.

It overrides a powerful magic method: __getattribute__.

🔹 2. Overriding __getattribute__

def __getattribute__(self, name):

    return self.x

✅ Explanation:

__getattribute__ is called for EVERY attribute access.

No matter what attribute you try to access (x, y, anything), this method runs.

🔍 Important Behavior:

When you do:

obj.x

Python internally does:

obj.__getattribute__("x")

🔹 3. Object Creation

obj = Test()

✅ Explanation:

An object obj of class Test is created.

No attributes are defined yet.

🔹 4. Accessing obj.x

print(obj.x)

🚨 What happens step-by-step:

Step 1:

obj.x

→ calls:

__getattribute__(self, "x")

Step 2:

Inside method:

return self.x

BUT ⚠️

self.x again triggers:

__getattribute__(self, "x")

Step 3: Loop Starts 🔁

This keeps happening:

__getattribute__ → self.x → __getattribute__ → self.x → ...

👉 Infinite recursion

🔹 5. Final Result

❌ Python stops execution with:

RecursionError: maximum recursion depth exceeded

🎯 Final Output

RecursionError
