Web scraping is a technique of extracting a large amount of data from the websites and arranging it so that it can be used in a variety of applications. Data that is found on the websites is presented in a format that is easier to collect and use it. For instance, data can be easily downloadable in comma-separated values (.csv) format. However, there are websites where data is not readily available for use. It can be obtained in PDF or a table, or it can be spread on different pages of a website. Web scraping enables you to extract the data manually or automatically and process or store it anywhere.
