bytearray.rjust(width[, fillbyte]) Return a copy of the object right justified in a sequence of length width. Padding is done using the specified fillbyte (default is an ASCII space). For bytes objects, the original sequence is returned if width is less than or equal to len(s). Note The bytearray version of this method does not operate in place - it always produces a new object, even if no changes were made.

typing.get_type_hints(obj) Return type hints for a function or method object. This is often the same as obj.__annotations__, but it handles forward references encoded as string literals, and if necessary adds Optional[t] if a default value equal to None is set.
