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.
