![]() ![]() This is important to note because we’ll be iterating through these pages later in this tutorial. However, you can also access the above page by using the same Internet Archive numeric string of the first page: The last page of Z artists has the following URL: In this case, there are 4 pages total, and the last artist listed at the time of writing is Zykmund, Václav. It is important to note for later how many pages total there are for the letter you are choosing to list, which you can discover by clicking through to the last page of artists. We’ll start by working with this first page, with the following URL for the letter Z: In the page above, we see that the first artist listed at the time of writing is Zabaglia, Niccola, which is a good thing to note for when we start pulling data. Let’s therefore choose one letter - in our example we’ll choose the letter Z - and we’ll see a page that looks like this: Since we’ll be doing this project in order to learn about web scraping with Beautiful Soup, we don’t need to pull too much data from the site, so let’s limit the scope of the artist data we are looking to scrape. The Internet Archive is a good tool to keep in mind when doing any kind of historical data scraping, including comparing across iterations of the same site and available data.īeneath the Internet Archive’s header, you’ll see a page that looks like this: This organization takes snapshots of websites to preserve sites’ histories, and we can currently access an older version of the National Gallery’s site that was available when this tutorial was first written. The Internet Archive is a non-profit digital library that provides free access to internet sites and other digital media. Note: The long URL above is due to this website having been archived by the Internet Archive. We would like to search the Index of Artists, which, at the time of updating this tutorial, is available via the Internet Archive’s Wayback Machine at the following URL: It holds over 120,000 pieces dated from the Renaissance to the present day done by more than 13,000 artists. The National Gallery is an art museum located on the National Mall in Washington, D.C. In this tutorial, we’ll be working with data from the official website of the National Gallery of Art in the United States. You should have the Requests and Beautiful Soup modules installed, which you can achieve by following our tutorial “ How To Work with Web Data Using Requests and Beautiful Soup with Python 3.” It would also be useful to have a working familiarity with these modules.Īdditionally, since we will be working with data scraped from the web, you should be comfortable with HTML structure and tagging. Prerequisitesīefore working on this tutorial, you should have a local or server-based Python programming environment set up on your machine. In this tutorial, we will collect and parse a web page in order to grab textual data and write the information we have gathered to a CSV file. Currently available as Beautiful Soup 4 and compatible with both Python 2.7 and Python 3, Beautiful Soup creates a parse tree from parsed HTML and XML documents (including documents with non-closed tags or tag soup and other malformed markup). ![]() In this tutorial we will be focusing on the Beautiful Soup module.īeautiful Soup, an allusion to the Mock Turtle’s song found in Chapter 10 of Lewis Carroll’s Alice’s Adventures in Wonderland, is a Python library that allows for quick turnaround on web scraping projects. ![]() The Python programming language is widely used in the data science community, and therefore has an ecosystem of modules and tools that you can use in your own projects. (See downside #1.Many data analysis, big data, and machine learning projects require scraping websites to gather the data that you’ll be working with. ![]() (An inconvenience if you, or someone to whom you send an archive, prefers to use a browser other than Safari a show-stopper if you send an archive to someone using anything other than Tiger-including Windows.) The second is that if you ever need to get at any of the content of an archive-images or text, for example-you must use Safari to first open the archive, then grab the content from there. The first is that these Web archives can be viewed only in Safari you can’t open them in another browser. This is a great feature however, it has two downsides. webarchive file in Safari and it will (roughly) look as if you were viewing the page normally via the Internet. You perform this task by viewing the desired Web page, choosing Save As from Safari’s File menu, and then choosing Web Archive from the Format pop-up menu in the Save dialog. One of the (welcome) additions to version 2 of Safari, included with Tiger, is the ability to save an entire Web page-text, images, and all-for offline viewing. ![]()
