Python Coding challenge - Day 372| What is the output of the following Python Code?

 



Code Explanation 

import weakref  

Imports the weakref module, which allows creating weak references to objects.

Weak references let Python track an object without preventing garbage collection (i.e., if there are no strong references left, the object is deleted).

class MyClass:  

    pass  

 Defines a simple class MyClass with no attributes or methods.

This is just a placeholder class to create objects.

obj = MyClass()  

Creates an instance obj of MyClass.

obj is a strong reference, meaning it keeps the object alive.

weak_obj = __________(obj)  

Creates a weak reference to obj using a function from the weakref module.

Final Output:

B) weakref.ref()
