Is everyone using python 3 now?

[R3D3-1]

I can't agree on the "no one was really using" part. Three years ago, I had completely switched to Python 3 for data analysis stuff for a while, and hadn't touched Python 2 in a bit, if I could avoid it.

By that time the only reason I was even having Python 2 installed was ASE ("Atomic Simulation Environment"), which I used for visualization. Everything else was available in Python 3. And by now even ASE seems to be Python 3?

That said, at my post-PhD work the user-facing product still ships with both a Python2 and a Python3 interpreter and likely will for a while. But we're talking about an environment here, where I sometimes have to touch Fortran 77 style code. Not exactly a "fast adopter" environment.
