An URL identifies a resource on the Internet. What is Urllib2? urllib2 is a Python module that can be used for fetching URLs. It defines functions and classes to help with URL actions (basic and digest authentication, redirections, cookies, etc) The magic starts with importing the urllib2 module. What is the difference between urllib and urllib2? How do you go getting files from your computer to S3? We have manually uploaded them through the S3 web interface. It’s reasonable, but we wanted to do better. So, we wrote a little Python 3 program that we use to put files into S3 buckets. If the bucket doesn’t yet exist, the program will create the bucket. Last but not least, we should include this line of code so that we can pause our code for a second so that we are not spamming the website with requests. This helps us avoid getting flagged as a spammer. time.sleep(1) Now that we understand how to download a file, let’s try downloading the entire set of data files with a for loop. The code urllib.request is a Python module for fetching URLs (Uniform Resource Locators). It offers a very simple interface, in the form of the urlopen function.
