Scraping Website: How to Write a Script in Python

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 How to Create Function

In Python, you can define and call the function. Once done, you can call it later from the other program. I have shared the structure of it. And, I have added the three rules of it; useful for interviews.

Rules to Create a Function

  1. A function definition is executable.
  2. The body will have the code to perform the task you wish.
  3. You can assign default parameter values.

1. Key Elements.

You will find here three key elements of the Python function. Here you can read the parameter vs argument differences.

Dream higher

Name of a function. It can be any valid identifier. It should be meaningful, and it should convey the work it will do.

Parameter. These should be separated with command and should be in the parentheses following the name of the function. The parameters are input to function. It can have any parameters.

Body of the function. The function body can contain code that implements the task to be performed by it.

2. Sample Function.

Life shrinks or expands in proportion to one’s courage

Python Example.

def product(num1, num2): 
# defined function name of product with two input parameters. 
# And this 'def' ends with ':' colon.

prod= num1*num2 
# multiplying two numbers num1 and num2 and assign to prod

print('The product of the numbers is \t:'+str(prod))
# prints product of two numbers

num1=int(input('Enter the first number\t:')) 
num2=int(input('Enter the second number\t:'))
return prod
# returns prod value to the calling program.

3. How to call a function.


myProduct = product(num1, num2)
# supply two arguments to the product function.

#The product function prints the product of two numbers.
