Closes: #6890 Some remarks, - `# coding ... utf-8` statements are not needed - isdigit on strings instead of a try-catch. - Default opening mode is read, so we can do `open()` without the `'r'` everywhere - Removed inheritinng from `object` class, it isn't necessary in python3. - `super(ClassName, self)` can now be replaced with `super()` - Use of itertools and `chain` on a couple places dealing with sets. - Used the operator module instead of lambdas when warranted `itemgetter(0)` instead of `lambda x: x[0]` `attrgetter('name')` instead of `lambda x: x.name` - `sorted` returns a list, so no need to use `list(sorted(...))` - Removed `dict()` using dictionary comprehensions whenever possible - Attempted to remove python3.2 support Signed-off-by: alexrecuenco <alejandrogonzalezrecuenco@gmail.com>
