Scraping Website: How to Write a Script in Python

Image
Here's a python script that you can use as a model to scrape a website. Python script The below logic uses BeautifulSoup Package for web scraping. import requests from bs4 import BeautifulSoup url = 'https://www.example.com' response = requests.get(url) soup = BeautifulSoup(response.text, 'html.parser') # Print the title of the webpage print(soup.title.text) # Print all the links in the webpage for link in soup.find_all('a'):     print(link.get('href')) In this script, we first import the Requests and Beautiful Soup libraries. We then define the URL we want to scrape and use the Requests library to send a GET request to that URL. We then pass the response text to Beautiful Soup to parse the HTML contents of the webpage. We then use Beautiful Soup to extract the title of the webpage and print it to the console. We also use a for loop to find all the links in the webpage and print their href attributes to the console. This is just a basic example, but

Python Interface Vs. Class: What's the Difference

Here are the differences between Class and Interface in Python.

Python interface


Python class can have all concrete methods. But interface does not have single concrete method.


Here you'll know about

  • What's abstract method
  • Abstract Class: How to Create it
  • Rules to Write an Interface
  • How to Create Abstract Class
  • How to Create an Interface


What's abstract method

The abstrcat method is one which does not have body.

from abc import ABC, abstract method
class name_class(ABC): # abstract class

@abstractmethod
def name_method(self): #abstract method without body
pass


The interface is used when all the features are needed to be implemented differently for different objects.

Rules to Write an Interface

  1. All methods of an interface should be abstract.
  2. You cannot create an interface object.
  3. If any class implements an interface, then you need to define all the methods given in that interface in child class.
  4. You need to declare all methods as abstract if that class does not implement the interface

How to Create Abstract Class


from abc import ABC, abstractmethod
class Myengineer(ABC):
@abstractmethod
def mybranch(self):
pass
myobj = Myengineer()


Output

TypeError: Can’t instantiate abstract class Myengineer
with abstract methods mybranch


How to Create an Interface

You cannot create an object from an abstract class. But you can do it by creating a child class.


from abc import ABC, abstractmethod

#Abstract class

class Myengineer(ABC):
@abstractmethod
def mybranch(self):
pass

#Child class implements abstract class

class MyEEE(Myengineer):
def mybranch(self):
print(“I am an electrical and electronics Engineer”)
myobj = MyEEE()
myobj.mybranch()
