Python Coding challenge - Day 955| What is the output of the following Python Code?

 

Code Explanation:

1. Defining the Base Class

class Processor:

A class named Processor is defined.

2. Making the Class Callable

    def __call__(self):

        return "proc"

The __call__ method makes objects of this class callable like functions.

When an instance is called (e.g., obj()), this method is executed.

It returns the string "proc".

3. Defining the Subclass

class Task(Processor):

Task inherits from Processor.

It inherits all behavior unless overridden.

4. Overriding __call__ in the Subclass

    def __call__(self):

        return super().__call__() + "_task"

Task overrides the __call__ method.

It calls the parent class's __call__ using super().

Takes its return value ("proc") and appends "_task".

So Task().__call__() returns "proc_task".

5. Calling the Object

print(Task()())

Step-by-step:

Task() creates an instance of Task.

The second () calls the instance, triggering Task.__call__.

Task.__call__ calls Processor.__call__ via super().

"proc" is returned and concatenated with "_task" → "proc_task".

print outputs "proc_task".

6. Final Output

proc_task

Final Answer

✔ Output:

proc_task
