Python Coding challenge - Day 709| What is the output of the following Python Code?

 

Code Explanation:

1) class B:

Defines a new class B.

Inside this class, we will have a class variable and two special methods.

2) val = 10

Declares a class variable val.

This variable belongs to the class itself, not to any instance.

Accessible via B.val or via cls.val inside a class method.

3) @staticmethod

@staticmethod

def s(): return 5

Marks s() as a static method.

Static methods do not receive self or cls.

They behave like normal functions, just namespaced inside the class.

Can be called via B.s() or via an instance (B().s()), but cannot access class or instance variables.

4) @classmethod

@classmethod

def c(cls): return cls.val

Marks c() as a class method.

Automatically receives cls, the class itself.

Can access class variables or other class methods, but cannot access instance variables.

In this case, cls.val refers to B.val (10).

5) print(B.s(), B.c())

B.s() → calls static method s() → returns 5.

B.c() → calls class method c() → accesses cls.val → returns 10.

Final Output

5 10
