Python Web Scraping Library
Web scraping is an exceptional tool for data extraction that enables decision-making, provides opinions, and can help you grow your business. Yet, at the same time, it can seem like a daunting task that requires a great deal of code writing. That does not have to be the case when you use the right Python web scraping library lineup.

In Python, web scraping libraries help to cut through the tedious tasks to amplify your overall ability to get started and adjust your scraping in a meaningful and effective way. As a result, it speeds up the process when you know which tools to use. In this guide, we will go over the best combination of Python web scraping libraries and how you can get started right away. Don’t overlook the fact that you can always get started using the Scraping Robot API right now, too.
What Are Python Libraries for Web Scraping?
Let’s first discuss what a Python library is. Python is made up of numerous individual, pre-written sets of code that allow you to have more of a plug-and-play style of functionality when creating code. In short, these modules provide reusable code that provides instructions. Libraries are pre-written functions and classes that allow you to put them in place quickly, so that you do not have to write all of those tedious components of code.
Python web scraping libraries are numerous. You can always choose those libraries you know how to use and feel best suited for your project. To help you, we have broken down the ideal Python web scraping framework here, outlining which are the best libraries for web scraping if you are using Python.
Beautiful Soup: The most popular Python web scraping library is Beautiful Soup. It is beneficial because it parses HTML and XML documents. When you use it as a component of your web scraping Python library setup, it can handle parsing and the creation of a parse tree. It also provides iteration, searching, and modifications of your parse tree.
Beautiful Soup is easy to learn and often takes just a few moments to download, learn, and start using it. It is best used on static web pages. Use BeautifulSoup when you want parsing HTML to be straightforward.
Scrapy: Another of the critical Python libraries for web scraping is Scrapy. Scrapy is a robust framework – it offers such an important arrangement of tools that it is generally the most important Python library for web scraping. It is highly scalable and offers efficient crawling. It is a complete toolset in one package, which is why it is often the best choice. In addition, it includes a robust scheduler and gives you ample options when it comes to storing scraped data.
We recommend using this web scraping Python library if you are working on a large-scale project that will handle requests, responses, and data extraction. It also offers tools for handling cookies and sessions. If you are scraping data from various formats and on more complex websites, Scrapy is an ideal option.
To help you decide between these first two tools, check out our tutorial: BeautifulSoup vs. Scrapy: Which Is Better for Web Scraping.
Selenium: The next Python web scraping library you should be familiar with and typically use is Selenium. It helps with one of the most tedious processes of web scraping – overcoming dynamic websites. Dynamic websites are tricky for web scraping because they often require you to input specific information or answer questions to move beyond the initial page to where the data you want lies. This can complicate the process overall. However, Selenium does a better job of web scraping when the data is loaded dynamically using JavaScript. It acts like a typical human when it comes to navigating the browser for the target website.
When you use this web scraping library in Python, it can click buttons, fill in forms, and successfully scrape dynamic web pages. If you are scraping pages with JavaScript, you can count on Selenium to be a helpful resource.
Playwright: Another option for dynamic web scraping is Playwright. As one of the best web scraping Python libraries for dynamic content, Playwright is a helpful tool for web scraping. It supports numerous browsers and various languages (if you want to move away from Python). To be effective, it does a great job of automating browser interactions. That speeds up the process while still getting around some of the more tedious tasks of inputting information and data.
You can use our tutorial, The Complete Guide to Playwright Web Scraping, if you are ready to incorporate this tool into your web scraping process. With minimal coding, it can be one of the most efficient browser automation tools available to you.
Requests: Requests are another essential web scraping library in Python. It is an excellent library for parsing HTML. Typically, you will combine Requests along with BeautifulSoup. Doing so will allow you to parse HTML data very quickly, and that can speed up your project. This makes the entire process more intuitive. Requests are very easy to use and offer a robust framework that can help you get started right away.
Requests will simplify your HTTP requests, supports sessions, cookies, and authentication, and has a very easy to understand (human readable) API. If you are downloading web pages and interacting with APIs, then Requests for web scraping is a must.
HTTPX: Perhaps one of the lesser-known web scraping libraries in Python options is HTTPX. It is a powerful HTTP client library for Python that has become rather commonly used for web scraping because it provides asynchronous functionality and http2 support. Many times, when choosing a Python web scraping library, there is a lot of work to do and time matters. With HTTPX, it is possible to speed up the web scraping process with the right setup.
How to Choose the Web Scraping Library in Python Best for Your Project
Which is the Python web scraping library you should use for your project? There is no simple solution that handles every situation well. The web scraping libraries for Python we listed here work well together to create a web scraping tool that can plow through data, no matter if you have a small-scale project or a massive, large-scale data extraction project to handle.
Python is the ideal choice for web scraping tasks of all types. To help you with choosing the best setup and web scraping Python library framework to use, consider the following tips:
Is your website rather simple: For simple, static websites, the best possible choice is BeautfiulSoup. The ease of use of this tool makes it a reliable option for just about any simple site. You can combine it with Requests to handle the entire process. Note that this combination is very commonly used and easy to learn if you do not have a lot of experience just yet.
Is your website complex: A complex website, one with an elaborate tree or one with thousands of pages, can still be done with BeautifulSoup, but you will find Scrapy to be a better Python web scraping library. When you plan to extract data from numerous pages, Scrapy offers the right level of functionality for most users.
Is the website dynamic: This is one of the most common growing concerns for web scraping. Dynamic websites can eliminate web scraping if you are not using the right web scraping library in Python. For dynamic sites, we recommend the use of Selenium or Playwright. Selenium tends to be the go-to because it has been around longer and is more well-known, but Playwright is easy to learn and faster.
Do you need to manage numerous requests at the same time: In this situation, HTTPX is an excellent choice because it offers asynchronous operation. This allows you to get more done when you have a lot of smaller tasks to handle.
Consider the Use of Proxies
Do not overlook the importance of proxies as a part of this process. A proxy is not a Python web scraping library but rather a tool to protect your identity and minimize failures of web scraping tools. If you have not done so yet, learn how to use a web scraping proxy to help you navigate the process. You can also use our tutorial, How to Set Up a Proxy: All You Need to Know, to get the process started.
