Yeah ok :) But the ancestors of penguins didn't wake up one morning, flap
their wings and fall out the tree, it happened gradually. Python2 syntax
could have been retained for X versions of 3 just as C++ keeps old stuff
until its eventually deprecated them removed.
Python 2 *was* retained for X versions of Python 3. From a quick check,
Python 3.0 was released in December 2008 and Python 2 support ended in
January 2020 - by which time Python 3 was up to 3.8 as ChrisA mentioned.
That's about an 11 year transition period, which is hardly sudden!
Python 3 *was* the point at which the features deprecated in Python 2
were removed.
The problem is, a lot seemed to ignore Python 3 for the first 12 years
and then suddenly panic because Python 2 support had ended.
