Python Coding challenge - Day 656| What is the output of the following Python Code?

 

Code Explanation:

1. Importing partial from functools

from functools import partial

This line imports the partial function from Python’s functools module.

partial allows you to fix some portion of a function’s arguments and generate a new function with fewer arguments.

2. Defining the function add

def add(x, y):

    return x + y

Defines a function named add that takes two parameters: x and y.

The function returns the sum of x and y.

3. Creating a new function add_five using partial

add_five = partial(add, y=5)

Uses partial to create a new function called add_five.

This new function has the argument y fixed to 5.

Essentially, add_five is equivalent to add(x, 5).

When you call add_five, you only need to provide the remaining argument x.

4. Calling add_five with an argument and printing the result

print(add_five(10))

Calls the new function add_five with x = 10.

Since y is already fixed to 5 by partial, this computes add(10, 5), which returns 15.

The result 15 is printed to the console.

Final Output:

15

Python Coding challenge - Day 378| What is the output of the following Python Code?

Code Explanation:

Importing ABC and abstractmethod

from abc import ABC, abstractmethod  

ABC (Abstract Base Class) is imported from the abc module.

@abstractmethod is used to define an abstract method.

Defining an Abstract Base Class (A)

class A(ABC):  

    @abstractmethod  

    def show(self):  

        pass  

A is an abstract class because it inherits from ABC.

show(self) is defined as an abstract method using @abstractmethod.

Since show() has no implementation (pass), any subclass of A must override it before it can be instantiated.

Creating a Concrete Subclass (B)

class B(A):  

    def show(self):  

        print("Hello")  

B is a subclass of A that implements the show() method.

Since B provides an implementation for show(), it can be instantiated.

Creating an Object and Calling show()

B().show()

B() creates an instance of class B.

.show() calls the show() method in B, which prints "Hello".

Since show() only prints but does not return anything, there is no None printed.

Final Output

Hello
