REF: -> Wiki Python2 or 3 <-
What are the differences?
Short version: Python 2.x is legacy, Python 3.x is the present and future of the language
While researching, I noticed that Weeman's product ,aka PhBot, has same development progress as Python.
LEGACY = Python 2.x , old stable phbot
PRESENT = Python 3.x , Stable Phbot
FUTURE = Python 3.x(DEV) , Testing Phbot.
Like in stubborn legacy users in python, there were members which insisted to use old stable version.
Once a wise man said , "Oldschool never dies!"
