Answer 3

You might want to check your regexp code with https://regex101.com/#JUMP_LINK__&&__python__&&__JUMP_LINK. It is an incredibly useful site!
Normally a () will return a group with the contents within.
( followed by a ?:, will create a non-capturing group, but will still match any character(s) behind it. in this case (?:c)

(a) = group1
(b......e) = group2
(d) = group3

so the length of it all is 3.

>>> import re
>>> test = re.compile('(a)(b(?:c)(d)(?:e))')
>>> match = test.search('abcde')
>>> match.groups()
('a', 'bcde', 'd')
>>> len(match.groups())
3
