[TriPython] Regular Expressions

[Chris Calloway]

Some observations to supplement the fine suggestions already put forward 
by the TriPython hive mind:

a) If you use an online regex tester with a Python search patter, be 
sure the tester supports Python re like this one:

https://regex101.com/

Many of the online testers are set up to use PCRE (Perl) by default.

b) See Rex Dwyer's fine presentation to TriPython about the new regex 
extentions:

c) When talking about text, please be sure to always specify whether 
Python 2 or Python 3.

d) If you can get your hands on the *first edition* of the O'Reilly 
regex book, about half of it is Python. Later editions entirely omit 
Python re.
