Address errors, improvements, formatting

- 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
