As more and more projects drop support of python 2.7 we will face such issues more frequently.
If I understand correctly this PR does not fix it in appveyor.
I think we should make some sprint in September to close as many current issues as possible, release 1.7.0 and drop python 2.7 support after it.

Thanks for the review @ssbarnea! 🍪

@insspb Lets not diverge, I hope we do not discuss dropping py27 before 2020. I use cookiecutter in molecule and I am sure I will not drop it until it ends EOL. Even after I am likely to keep it until I am forced to drop it. I am more likely to replace a library that drops support for it than dropping support for py27.
