Python Coding challenge - Day 377| What is the output of the following Python Code?


Code Explanation 

class Meta(type):

    pass

Defines a custom metaclass Meta, which inherits from type.

In Python, metaclasses control how classes are created.

Meta is now a metaclass, meaning it can be used to define new classes.

class A(metaclass=Meta):

    pass

Defines a new class A using Meta as its metaclass.

Normally, Python uses type as the default metaclass.

Here, A is created using Meta instead of type, meaning:

Meta is responsible for handling the creation of A.

A is now an instance of Meta, instead of type.

print(type(A))

Prints the type of A

Since A was created using Meta, the result will be:

Final Output:

<class '__main__.Meta'>
