Re: Removal of old Python2-era stuff

Hi Claude,

applied this and it worked fine for my tests, but on jenkins I was still testing with 3.6 and it turns out that the re 
module did not have a Patterns class, but instead it has _sre.SRE_Pattern so I will revert that small change in 
validators.py for now.

In practice I think we have stopped building 3.6 wheels at present because I got some weird errors about failures from 
the reportlab-mirror build wheels action.
