I'm not %100 sure that's really an accurate assessment of the slow uptake in Python3.  Regardless, the clock is ticking on the 2.x codebase as it is reaching EOL status in 2020: https://www.python.org/dev/peps/pep-0373/ Hopefully a solid deadline (which has already been pushed back) will motivate developers to accelerate the task of migrating to py3 sooner rather than later. -pete -- Pete Wright pete@nomadlogic.org @nomadlogicLA
