So with the release of MagPi issue 57 it came equipped with some hardware provided in partnership with Google to aid in creating a Google Home<\/a>\u00a0type device.<\/p>\n

Obviously a bit more basic but with the ability to update it and make it your own.<\/p>\n

Out the box what is provided is fine, but you get thinking about what you want it to do, and what I wanted was a way for it to tell me the top 10 news headlines from the BBC for the UK.<\/p>\n

So by updating the action.py file I created a new class called ReadRssFeed, so instead of only reading the headlines of bbc I can now have it to read any rss feed.<\/p>\n

The code is early stages and needs some changing to make it a bit more dynamic but it will give you an idea of what to do.<\/p>\n

The Code<\/strong><\/p>\n

\r\n# Feedparser is used to parse the rss feeds (for more information view this for a good intro http:\/\/www.pythonforbeginners.com\/feedparser\/using-feedparser-in-python)\r\n# Use pip to install feedparser (sudo pip install feedparser)\r\n# include this at the top of the action.py\r\nimport feedparser\r\n\r\n#this is the class to read rss feeds (add under the section of \"Makers!

Hopefully this is of some use to someone else as well. Any updates I do I will post back up here so everyone is aware.<\/p>\n","protected":false},"excerpt":{"rendered":"
