Python download file requests how to#
We have explained how to use urllib module to download remote files. You should see the downloaded document as “cat2.jpg” Conclusion You can get direct access to the raw response (and even the socket), if needed as well. 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. gz files with requests in Python without decoding it As discussed in the comments above, this seems to have solved the issue: From the docs for the requests module: Requests automatically decompresses gzip-encoded responses. 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.
