Web Scraping Basics What is web scraping all about?
This is where Python and web scraping come in. Web scraping is about downloading structured data from the web, selecting some of that data, and passing along what you selected to another process.
In this tutorial, you will be writing a Python program that downloads the list of mathematicians and their XTools pages, selects data about their popularity, and finishes by telling us the top 5 most popular mathematicians of all time!
Feel free to set things up however you like. Here is how I tend to do it: Get started by including these import statements at the top: The requests package comes to the rescue. In this tutorial, you will need only the requests. This function just prints them, but you can make it do anything.
If nothing goes wrong, you end up with the raw HTML content for the page you requested. If there were any problems with your request like the URL is bad, or the remote server is downthen your function returns None. The closing function ensures that any network resources are freed when they go out of scope in that with block.

I usually look for id or class element attributes or any other information that uniquely identifies the information I want to extract. To make matters concrete, turn to the list of mathematicians you saw earlier. With this information in mind, you can write your function to extract a single list of names: Finally, you convert the set to a list and return it.
Now that you have a list of names, you need to pick out the pageviews for each one. The function you write is similar to the function you made to get the list of names, only now you supply a name and pick out an integer value from the page.
The plan is simple: Working with real-world data is messy, and trying to force messy data into a uniform shape will invariably result in the occasional error jumping in to mess with your nice clean vision of how things ought to be.
