Michael Selik 2702638eab bpo-34002: Minor efficiency and clarity improvements in email package. (GH-7999) ... * Check intersection of two sets explicitly Comparing ``len(a) > ``len(a - b)`` is essentially looking for an intersection between the two sets. If set ``b`` does not intersect ``a`` then ``len(a - b)`` will be equal to ``len(a)``. This logic is more clearly expressed as ``a & b``. * Change while/pop to a for-loop Copying the list, then repeatedly popping the first element was unnecessarily slow. I also cleaned up a couple other inefficiencies. There's no need to unpack a tuple, then re-pack and append it. The list can be created with the first element instead of empty. Secondly, the ``endswith`` method returns a bool, so there's no need for an if- statement to set ``encoding`` to True or False. * Use set.intersection to check for intersections ``a.intersection(b)`` method is more clear of purpose than ``not a.isdisjoint(b)`` and avoids an unnecessary set construction that ``a & set(b)`` performs. * Use not isdisjoint instead of intersection While it reads slightly worse, the isdisjoint method will stop when it finds a counterexample and returns a bool, rather than looping over the entire iterable and constructing a new set.		2019-09-19 20:25:55 -07:00
