- Removed unused code not portable due to buffer() use - raw_input() does not exist in Python 3 - Fixed octal constant syntax for Python 3 - Fixed TypeError - Replace if not exists: makedirs(path) with single call: using makedirs(path, exist_ok=True) - Class inherits from object, can be safely removed from bases in python3: pylint's useless-object-inheritance (W0235) check Signed-off-by: JoeLametta <JoeLametta@users.noreply.github.com>
