Python Coding challenge - Day 957| What is the output of the following Python Code?

 

Code Explanation:

1. Defining the Class

class Safe:

A class named Safe is defined.

2. Overriding __getattribute__

    def __getattribute__(self, name):

        if name == "open":

            return super().__getattribute__(name)

        return "blocked"

__getattribute__ is called for every attribute access on an instance.

It receives:

self → the instance

name → the name of the attribute being accessed

Logic:

If the attribute name is "open", delegate to Python’s normal lookup using super().__getattribute__.

For any other attribute, return the string "blocked" instead of the real value.

So:

s.open → real method

s.x, s.anything_else → "blocked"

3. Defining the open Method

    def open(self):

        return "ok"

A normal instance method that returns "ok".

4. Creating an Object

s = Safe()

Creates an instance of Safe.

5. Accessing Attributes

print(s.open(), s.x)

Let’s evaluate each part:

▶ s.open()

s.open triggers __getattribute__(s, "open").

Since name == "open", it calls super().__getattribute__("open").

That returns the actual method open.

() calls it → returns "ok".

▶ s.x

s.x triggers __getattribute__(s, "x").

"x" ≠ "open", so it returns "blocked".

No error is raised.

6. Final Output

ok blocked

Final Answer

✔ Output:

ok blocked
