I'm just starting a new Python project, and ideally I'd like to offer Python 2 and 3 support from the start, with minimal developmental overhead. My question is, what is the best way of doing this for brand new projects?
I have come across projects that run 2to3, or even 3to2, as part of their installation script. This seems to be a very common way. However, there seems to be several different ways of doing this. I also came across Distribute.
There is also the option of trying to write polyglot Python 2/Python 3 code. Even though this seems like a horrible idea, I have noticed that I tend to write code lately that is more idiomatic as Python 3 code, even though I still run it as Python 2. I have a feeling this only helps my own transition when the day finally arrives, and doesn't do much for offering or at least helping dual support though.
Most of the projects offering dual support that I have seen added Python 3 support late, so I'm especially curious if there is a better way that is more suited for new projects, where you have the benefit of a clean slate.
Thanks!
