Although we've answered Eric's original question to over the hills and far away and all the way back, I feel compelled to point out that python 2.7's end-of-life support is on the horizon: https://pythonclock.org/ While existing python 2.x installations won't turn into pumpkins in 2020, you won't be getting the benefit of updates. cheers, AC On Wed, Mar 7, 2018 at 3:35 PM, Bryan Brown <[log in to unmask]> wrote: > Hi Eric, > > > Unless you are specifically working on a legacy project written in Python > 2 that is to large to update, I would strongly recommend working with 3 as > its the future.
