syntax fixups suggested by PyCharm

Drop unneeded parens.
Drop trailing semicolons.
Triple double-quote docstrings.
Regexes drop unneeded escapes.
Spaces around parens, braces: remove/add.
Some one-tuples get their missing closing comma.
A couple of sets use set init syntax {foo} instead of set([iter]) now.
And a fiddle in Node to reduce lookup time on md5 signature functions
 (came about because of a line-too-long issue, initially)
