More coding style cleanup

Fixing more issues found with pylint.  Some that were supposed to
have been fixed in the previous sweep (Ie0db839e) but were missed:

C0321: More than one statement on a single line
W0622: Redefining built-in 'name'

And some more:

W0631: Using possibly undefined loop variable 'name'
W0223: Method 'name' is abstract in class 'name' but is not overridden
W0231: __init__ method from base class 'name' is not called
