Pythons’ urllib library offers a range of functions designed to handle common URL-related tasks. We use the with statement because it will automatically close a file and simplifies the code. Then you just take the requests object and call its content property to get the data you want to write. The requests library method is get, which corresponds to the HTTP GET. In fact, you could reduce that part of the script by one line by just doing the following: Įither way, it works quite well. For urllib2, you just have to open the url and then read it and write the data out. On the other hand, the other two libraries are very simple too. requestsfile-1.5.1-py2.p圓-none-any.whl (3.7 kB view hashes ) Uploaded py2 p圓. requests-file-1.5.1.tar.gz (5.7 kB view hashes ) Uploaded source. It’s simplicity makes it very easy to use. If you're not sure which to choose, learn more about installing packages. Let’s take a look: import urllibĪs you can see, urllib is just a one-liner. We will download a zipped file from this very blog for our example script. need to resume an HTTP download of a file that has been partially transferred. Since this is a pretty simple task, we’ll just show a quick and dirty script that downloads the same file with each library and names the result slightly differently. We’ll be focusing on the two urllib modules and requests for this article.
