python for web scr~ping
consider the following scenario: you need to pull a large amount of data from websites as quickly as possible. how would you do it if you didn’t go to each website and manually collect the data? ok, the response is “web scr~ping.” scr~ping the web makes this job a lot easier and faster
our web scr~ping services provides high~quality structured data to improve business outcomes and enable intelligent decision making
our web scr~ping service allows you to scr~pe data from any websites and transfer web pages into an easy~to~use format such as excel, csv, json and many others
in this article on web scr~ping with python, you’ll learn the basics of web scr~ping and see a demonstration of how to extract data from a website. i’ll be talking about the following topics:
what is the purpose of web scr~ping?
what is web scr~ping and how does it work?
is it legal to scr~pe data from the internet?
why is python useful for scr~ping the web?
what is the best way to scr~pe data from a website?
web scr~ping libraries are libraries that are used to scr~pe data from the internet

what is the purpose of web scr~ping?
web scr~ping is a technique for extracting vast amounts of data from websites. but why is it necessary to obtain such vast amounts of data from websites? take a look at the following web scr~ping software to learn more:
web scr~ping is used by services like p~rs~hub to gather data from online shopping websites and use it to compare product prices
web scr~ping is used by several businesses that use email as a marketing tool to collect email addresses and then submit bulk emails
web scr~ping is used to gather data from social media platforms such as twitter in order to determine what’s trending
web scr~ping is used to gather a large amount of data (statistics, general information, temperature, and so on) from websites, which is then processed and used in surveys or r&d
job postings: information about job openings and interviews is gathered from various websites and then compiled in one location so that it is readily available to the user
what is the concept of web scr~ping?
web scr~ping is a tool for extracting vast quantities of data from websites that is automated. the information on the websites is not organised. web scr~ping aids in the collection of unstructured data and its subsequent storage in a standardised format. scr~ping websites can be done in a variety of ways, including using online services, apis, or writing your own code. in this post, we’ll look at how to use python to implement web scr~ping

is it legal to scr~pe data from the internet?
when it comes to whether or not web scr~ping is legal, some websites allow it while others do not. you should check the “robots.txt” file on a website to see whether it allows web scr~ping or not. by appending “/robots.txt” to the url you want to scr~pe, you will find this file. i’m scr~ping the flipkart website for this example. the url for viewing the “robots.txt” file is www.flipkart.com/robots.txt
learn everything there is to know about python and its many applications
why is python a good web scr~ping language?
the following is a list of python features that make it more appropriate for web scr~ping
python is an easy language to programme in. there are no semi~colons “;” or curly~braces “” needed anywhere. this makes it easier to use and less messy
python has a large set of libraries, such as numpy, matplotlib, pandas, and others, that provide methods and services for a variety of purposes. as a result, it’s perfect for site crawling and more data manipulation
dynamically typed: you don’t have to specify datatypes for variables in python; you can just use them wherever they’re needed. this saves you time and speeds up your work
python syntax is simple to understand, owing to the fact that reading a python code is very similar to reading a statement in english. python’s indentation lets the user distinguish between various scopes/blocks in the code, making it expressive and easy to read
web scr~ping is a time~saving technique that uses a small amount of code to accomplish a big task. but what good is it if you waste more time writing code? you don’t have to, though. small codes can be written in python to accomplish big tasks. as a result, even when writing the code, you save time
what if you get into trouble while writing the code? you don’t have to be concerned. python has one of the largest and most active groups in the world, where you can get support
what is the best way to scr~pe data from a website?
when you run the web scr~ping code, it sends a request to the url you specified. the server sends the data in response to your request, allowing you to read the html or xml page. the code then p~rs~s the html or xml page, locating and extracting the data
you must follow these simple steps to extract data using web scr~ping with python:
locate the url you want to scr~pe
examining the page
locate the information you want to extract
make the code
execute the code to get the results
save the data in the appropriate format
let’s look at how to use python to extract data from the flipkart website
web scr~ping libraries are libraries that are used to scr~pe data from the internet
python, as we all know, has a wide range of applications and libraries for various purposes. the following libraries will be included in our next demonstration:
curriculum of the course
certification in python programming
selenium is an open~source web testing framework. it’s a programme that automates browser functions
beautifulsoup is a python package that allows you to p~rs~ html and xml documents. it generates p~rs~ trees, which are useful for quickly extracting data
pandas: pandas is a data manipulation and ~n~lysis library. it’s used to collect data and save it in the format that you want

scr~ping the flipkart website as an example of web scr~ping
pre~requisites include:
python 2.x or python 3.x installed with selenium, beautifulsoup, and pandas libraries
chrome is a browser developed by google
ubuntu is a linux~based operating system
let’s get this party started!
step 1: locate the url you wish to scr~pe
we’ll scr~pe the flipkart website to get the price, name, and rating of laptops for this example. this page can be found at https://www.flipkart.com/laptops/buyback~guarantee~on~laptops/pr? sid=6bo percent 2cb5g&uniqbstoreparam1=val1&wid=11.productcard.pmu v2&uniqbstoreparam1=val1&wid=11.productcard.pmu v2
step 2: examining the web page
in most cases, the data is nested in tags. so we examine the page to see where the data we want to scr~pe is nested under which name. simply right~cl!ck on an element and select “inspect” from the drop~down menu

when you select the “inspect” b~tton, a “browser inspector box” will appear

step 3: locate the information you want to extract
let’s extract the price, name, and rating from the “div” tag, which are all in the “div” tag
