Shall we stay on the list? My plan:

(1) Release Biopython 1.76 with Python 2.7 and 3.5 support
(2) Turn off testing under Python 2.7 and 3.5

Then tackle the low handing fruit (in no particular order):

(3) Remove Bio._py3k compatibility shim
(4) Look for and remove other Python 2 specific workarounds
(5) Remove no longer needed __future__ imports etc
(6) Remove all the Python 2/3 overhead in the C code

Also, where sensible and after appropriate discussion, take
advantage of new language or standard library features in
Python 3.6+ as appropriate (e.g. sorted dictionaries by default
without needing to import OrderedDict from collections).

I hadn't thought much about f-strings (beyond that I'm not
used to them and that makes me dislike them), but that could
be a good example.
