“You can speak Python and helped with porting stuff to Python 3.”
The Parselmouth badge is categorized as a “Miscellaneous Badge” and was defined in this Trac ticket. But what’s the real scoop behind the Parselmouth badge?
In short, Parselmouth is awarded to Fedora contributors who assist in porting Python 2 packages in Fedora to Python 3. As of present date, the current version of Fedora (Fedora 23) defaults to using Python 3 for new installs. While Python 2 is easily installed, there are still a large number of packages that are not up to date to using the latest version of the language. As recognized by the developers of the programming language and the countless that use it, Python 3 is the future, and it is important that Fedora helps lead the way towards making Python 3 the standard.
