chore(refactor): multiple changes/cleanups
Simplify 'for x in [list val]; alist.append(x)' to 'alist = list([list
val])'. Easier to read as copy of list. Also twice as fast although
speed not an issue.
Remove unneeded list() wrappers. Replace set(list comprehension) with
set comprehension.
Also add trailing ,'s to last element in tuples/lists.
Add some noqa items for acceptable operations in context.
Switch " ... \" ...\" ..." to: ' ... " ... " ...' to remove need to
escape internal '"'.
Change 'not x in y' to 'x not in y'.
