Python Coding challenge - Day 284| What is the output of the following Python Code?

 

 Code Explanation:

1. Class Definition

class MyClass:

A class named MyClass is defined. Classes in Python are blueprints for creating objects, but they can also contain methods that can be called without creating an instance of the class.

2. @classmethod Decorator

@classmethod

def hello(cls): 

The @classmethod decorator makes the method hello a class method.

Class methods:

Take the class itself as the first argument, which is conventionally named cls.

Can be called directly on the class without requiring an instance.

Here, cls refers to the class MyClass.

3. The Method Implementation

print(f"Hello from {cls.__name__}")

Inside the hello method:

The cls parameter gives access to the class object.

cls.__name__ retrieves the name of the class (MyClass in this case).

The print statement outputs a message using the class name.

4. Calling the Class Method

MyClass.hello()

The class method hello is called directly on the class MyClass, without creating an instance.

The cls parameter inside the method refers to MyClass.

Output:

Hello from MyClass
