Of-course I tried: that is why I used “had to”. The library itself and
libraries it depends on are only existing in a 2 version (at the
moment). I write code that should work in 2 and 3 both as long as 2 is
still a significant part. I call programs with python3 (even while it
is 10 to 20 percent slower) and only when that is not possible I use
Python 2. (Except to test if code also works with Python 2.)
