adding Python 3 support

[cgoldberg]

Hi @peterlevi ,
Do you have plans for porting variety-slideshow to Python 3? If not, would you be willing to accept a PR if I contributed it?

The only dependency used in variety is the gi package... and python3-gi has been in the Ubuntu archive since 12.04. Besides gi.repository, the variety codebase uses only standard library modules... so that would be a straight forward effort to support Python 3.

There are basically 2 ways to approach Python 3 compatibility:

1. convert entire source to Python 3 syntax and drop Python 2 support
2. modify variety-slideshow so there is a single codebase that supports both Python2 and Python3 (with conditional imports and such)

Which way would you like to see variety go?

Thanks!

Hi @cgoldberg,

Sorry for slow response, quite busy with work recently, not much time for the personal projects. But I'm happy to hear there's contributors' interest!

I hadn't planned on porting to Python 3, but, yes, I would accept a PR that makes it support both Python 2 and 3. Dropping Python 2 is a no-go for now, because variety-slideshow is (to some extent) part of Variety (https://launchpad.net/variety) which is Python 2 only, no plans to port that one for now, and I'd prefer Variety + Slideshow combined to require one Python version only on the machine, not both.

Thanks,
Peter
