Now, as mentioned above in the introduction, we'll need to emulate our browser to scrape sites like Amazon. Let's import Beautiful Soup next by typing into our Python script: from bs4 import BeautifulSoup

To install it, type in your terminal: pip3 install beautifulsoup4 With that, I'd like to introduce Beautiful Soup! Beautiful Soup is a highly versatile library that allows us to manage the HTML we extract. Here, we're going to install another important library, one that allows us to interact and explore the HTML we parsed with requests. To do that, open main.py and type at the top: import requests In order to use requests, we must import it into our Python script. If you're using Windows, pip should work just fine as well. To install it, fire up your terminal and type: pip3 install requests
This library effectively allows our script to talk to and play nice with the Internet website, downloading its contents.

In order to extract our target site's HTML code into our Python script, we're going to want to install Python's requests library. Personally, mine is Visual Studio Code, but even Windows Notepad or Mac TextEdit will do the job just fine. Let's create a new main.py file in your favorite IDE. Now, you've got a working Python setup on your computer that you can run your scripts on. If you're on macOS, follow this tutorial. Sudo apt install python3 python3-pip ipython3 Once you've got WSL set up on Windows, and/or you've got a terminal running and ready to go on Windows/Linux, type the following in your terminal: Sounds cool right? Let's jump right in! Setting Up Terminal Environment, Files & Libraries
they can type in Microsoft Surface), then our scraper will scrape three retailers (eBay, Amazon, and Best Buy) for the cheapest, most popular price, then it will return this price and a link to the purchase page. Firstly, our script will gather user input for a product they might be interested (ex.
With all of this in mind, here's the action plan for this tutorial. Yet, as long as we're not spamming them with millions of requests at once, we're okay to crawl their pages and web scraping is indeed ethical in this case. There's a few reasons as to why these sites dislike web scrapers, as scrapers tend to take a hit in server performance and overload them. These types of sites dislike users from crawling and scraping their pages, but we'll get into a few workarounds that will allow us to emulate a browser and give us scraping access. However, some sites are harder to scrape than others. If you want to pull the name or other details of a YouTube video and display it in your Python program, you're effectively web scraping a YouTube link on the Internet. So with that, you may ask, what is a web scraper and how useful it is?īasically, web scraping allows us to "scrape," or retrieve data and text from websites on the Internet. Introduction The Art of Web Scrapingīefore we delve into web scraping with the Python programming language, we'll need to understand the fundamentals of web scraping.

In addition, I recommend learning how to use your browser's developer tools (F12) to select HTML elements on a website, as you'll be doing that quite a lot in this tutorial. If you're on Windows, do install the Windows Subsystem for Linux (WSL), as that will make life a lot easier when running Python scripts (macOS and Linux users, you're all good to go). Before you learn how to scrape the web, you should probably be familiar with basic Python and HTML.
