INTRODUCTION

Web scraping is the automated data extraction from websites. There are two types of web scraping: content scraping and structure scraping. Content scraping extracts textual content from a website’s pages, whereas structure scraping involves removing relational data from HTML objects.

A web scraper is an agent that performs web scraping to extract information for further use.

The use of web scrapers can be diverse, such as monitoring online trends or news, updating existing data sets by extracting information from websites and analyzing them further, maintaining sites, detecting broken links, and correcting them.

In addition to being done manually, the software is generally used to automate it. Python is a popular language for web scraping because it has several libraries that make it easy to scrape data from websites.
