The optional timeout parameter specifies a timeout in seconds for blocking operations like the connection attempt (if not specified, the global default timeout setting will be used). urllib2 module sends HTTP/1.1 requests with Connection:close header included. data should be a buffer in the standard application/x-function takes a mapping or sequence of 2-tuples and returns a string in this format. Currently HTTP requests are the only ones that use data the HTTP request will be a POST instead of a GET when the data parameter is provided. Open the URL url, which can be either a string or a Request object.ĭata may be a string specifying additional data to send to the server, or None if no such data is needed. The urllib2 module defines the following functions: urllib2.urlopen(url]]]]) Please consider to donate us if you find the blog useful.The Requests package is recommended for a higher-level HTTP client interface.

We have explained how to use urllib module to download remote files. You should see the downloaded document as “cat2.jpg” Conclusion

Here “wb” states that the open method should have permission to write binary data to the given file.Įxecute the above script and go to your “~/Downloads/tmp” directory. The open method accepts two parameters, the path to the local file and the mode in which data will be written.

With open('/Users/tnguyen/Downloads/tmp/cat2.jpg', 'wb') as f: Therefore, the snippet below works only in Python 2. Keep in mind that you can pass any filename as the second parameter and that is the location and name that your file will have, assuming you have the correct permissions. Finally, we call the urlretrieve method and pass it the url variable as the first argument, “/Users/tnguyen/Downloads/tmp/cat.jpg” as the second parameter for the file’s destination. Next, we create a variable url that contains the path of the file to be downloaded. In the earlier snippet, we first import the urllib.requestmodule. (url, '/Users/tnguyen/Downloads/tmp/cat.jpg') Print('Beginning file download with urllib2.') This script works only in Python 3 import urllib.request How to do Using the urllib.request package in Python 3 We’ve included it here due to is popularity in Python 2. Because of this, we wouldn’t recommend using it in favour of one of the methods below. Note: This is considered a “legacy interface” in Python 3, and it may be deprecated at some point in the future.

However, we believe that it can be useful to know how to open URLs and interact with them without using a 3rd party and it may also help you appreciate why the requests package is so popular. The official documentation actually recommends that you might want to check out the 3rd party library, requests, for a higher-level HTTP client interface. We will be covering each part individually except for urllib.error. The current version of urllib is made up of the following modules: These are now a part of the urllib package in Python 3. If you are coming from a Python 2 background you will note that in Python 2 you had urllib and urllib2. The urllib module in Python 3 is a collection of modules that you can use for working with URLs.

In other words, you won’t find urllib2 in Python 3 instead of urllib. The urllib module is the replacement of urllib2 as long as migrating from Python 2 to Python 3. Using the urllib.request package in Python 3.
