go back  49 - Contribute to Open Source: Clean up Planet Python

This challenge write-up first appeared on PyBites.

Hi Pythonistas, it has been silent on the Community Blog challenges front, but then again we completed the 100 Days of Code in Python course which was a great milestone. Although less frequent, we will however, keep doing blog challenges so not to worry! Let's start with a long pending item: cleaning up Python planets feeds, an interesting and valuable open source contribution.

The Challenge

See issue 233: there are a lot of feeds that are invalid or outdated. For this Challenge you're to write a script that does the cleaning as per requirements stated in the issue:

  • Run weekly or monthly
  • Iterate all urls on config.ini and also python libraries and python planets list
  • Call each URL and assert (following redirects) -
    • Check return code is 200
    • Check data of last update is newer than one year
    • Check feed is valid using feedvalidator/podcastvalidator/othervalidator
  • If not valid, store the URL in a simple database (text file, sqlite or something)
    • ACTION: If link returns bad status\invalid 3 times, remove from planet
    • ACTION: If feed is outdated for more than one year, keep in planet but remove from sidebar
    • ACTION: If feed is updated and not in sidebar, put it there again


Ours and potentially a lot of other feeds are not showing up due to what seems to be an SSL issue. Can you solve it and make a lot of Pythonistas happy? Check our inital debugging on issue 135 and feel free to chime in (be warned though: might require some very old Python 2.x ...)
