This module can be used to generate web feeds in both ATOM and RSS format. It has support for extensions. Included is for example an extension to produce Podcasts.

It is licensed under the terms of both, the FreeBSD license and the LGPLv3+. Choose the one which is more convenient for you. For more details have a look at license.bsd and license.lgpl.

Prebuild packages

If your distribution includes this project as package, like Fedora Linux does, you can simply use your package manager to install the package. For example::

$ dnf install python3-feedgen

Using pip

You can also use pip to install the feedgen module. Simply run::

$ pip install feedgen

Create a Feed

To create a feed simply instantiate the FeedGenerator class and insert some data:

.. code-block:: python

from feedgen.feed import FeedGenerator
fg = FeedGenerator()'')
fg.title('Some Testfeed') {'name':'John Doe','email':'[email protected]'} ) href='', rel='alternate' )
fg.subtitle('This is a cool feed!') href='', rel='self' )

Note that for the methods which set fields that can occur more than once in a feed you can use all of the following ways to provide data:

  • Provide the data for that element as keyword arguments
  • Provide the data for that element as dictionary
  • Provide a list of dictionaries with the data for several elements


.. code-block:: python

fg.contributor( name='John Doe', email='[email protected]' )
fg.contributor({'name':'John Doe', 'email':'[email protected]'})
fg.contributor([{'name':'John Doe', 'email':'[email protected]'}, ...])

Generate the Feed

After that you can generate both RSS or ATOM by calling the respective method:

.. code-block:: python

atomfeed = fg.atom_str(pretty=True) # Get the ATOM feed as string
rssfeed  = fg.rss_str(pretty=True) # Get the RSS feed as string
fg.atom_file('atom.xml') # Write the ATOM feed to a file
fg.rss_file('rss.xml') # Write the RSS feed to a file

Add Feed Entries

To add entries (items) to a feed you need to create new FeedEntry objects and append them to the list of entries in the FeedGenerator. The most convenient way to go is to use the FeedGenerator itself for the instantiation of the FeedEntry object:

.. code-block:: python

fe = fg.add_entry()'')
fe.title('The First Episode')"")

The FeedGenerator's method

will generate a new FeedEntry object, automatically append it to the feeds internal list of entries and return it, so that additional data can be added.


The FeedGenerator supports extensions to include additional data into the XML structure of the feeds. Extensions can be loaded like this:

.. code-block:: python

fg.load_extension('someext', atom=True, rss=True)

This example would try to load the extension “someext” from the file

. It is required that
contains a class named “SomextExtension” which is required to have at least the two methods
. Although not required, it is strongly suggested to use
as superclass.

load_extension('someext', ...)
will also try to load a class named “SomextEntryExtension” for every entry of the feed. This class can be located either in the same file as SomextExtension or in
which is suggested especially for large extensions.

The parameters

control if the extension is used for ATOM and RSS feeds respectively. The default value for both parameters is
, meaning the extension is used for both kinds of feeds.

Example: Producing a Podcast

One extension already provided is the podcast extension. A podcast is an RSS feed with some additional elements for ITunes.

To produce a podcast simply load the


.. code-block:: python

from feedgen.feed import FeedGenerator
fg = FeedGenerator()
fg.podcast.itunes_category('Technology', 'Podcasting')
fe = fg.add_entry()'')
fe.title('The First Episode')
fe.description('Enjoy our first episode.')
fe.enclosure('', 0, 'audio/mpeg')

If the FeedGenerator class is used to load an extension, it is automatically loaded for every feed entry as well. You can, however, load an extension for a specific FeedEntry only by calling

on that entry.

Even if extensions are loaded, they can be temporarily disabled during the feed generation by calling the generating method with the keyword argument

set to

Custom Extensions

If you want to load custom extensions which are not part of the feedgen package, you can use the method

instead. You can directly pass the classes for the feed and the entry extension to this method meaning that you can define them everywhere.

Testing the Generator

You can test the module by simply executing::

$ python -m feedgen

If you want to have a look at the code for this test to have a working code example for a whole feed generation process, you can find it in the
