Do you want to learn how to build web scrapers using Python? Come in now and read our article on how to build a simple web scraper. Codes, together with explanations included.<\/p>\n<\/blockquote>\n

\"Web\n<\/picture>\n

Have you ever wondered how programmers build web scrapers for extracting data from websites? If you have, then this article has been written specifically for you.<\/p>\n

It is no longer news that we live in a data-driven world, and much of the data required by businesses can be found only. By using automation bots known as web scrapers, you can pull required data from websites at high speed.<\/p>\n

\n

Google does it, so does Yahoo, Semrush, Ahref, and many other data-driven websites.<\/p>\n<\/blockquote>\n

I am going to show you how you can start building a web scraper. No, it is not going to be high-end like that of Google. It can\u2019t even be compared to many production-ready web scrapers.<\/p>\n

But it is going to be a useful tool that you can use straight away. I choose to build this web scraper for this tutorial because it is something I can personally use \u2013 and it is simple to build. Let start with the problem definition.<\/p>\n\n

<\/span>Problem Definition<\/strong><\/span><\/h2>\n

Build a web scraper that scrapes Google related keywords and write them into a text file. In essence, what we would be building is an SEO tool<\/a> that accepts a search keyword as input and then scrapes the related keywords for you. Just in case you do not know, Google related keywords are keyword suggestions found below search engine listing.<\/p>\n

\"Python\n<\/picture>\n

The keywords are related to the search keyword you entered into Google search and can be incorporated into an article related to the keyword search for SEO purposes.<\/p>\n

There are many paid tools that do this in the market but have other functionalities that our own do not. Because it has been built for a tutorial, I stripped out all the complexities, and this means no exception (error) handling. If you enter a keyword without related keywords, it will throw an exception, and the program will crash.<\/p>\n\n

<\/span>Requirements<\/strong><\/span><\/h2>\n

Even though the tutorial is a beginner level tutorial, I expect you to know how to code a little bit in Python<\/a>. You should know the Python data structures such as integer, string, list, tuple, and dictionary. You should also know how to loop through a list using the for-in loop.<\/p>\n

Know how to create functions and classes as the code is written in Object-Oriented Programming (OOP) paradigm. You are also expected to know how to read and write HTML for the inspection of data to be scraped.<\/p>\n

The required dependencies are only two \u2013 requests and BeautifulSoup.<\/p>\n
