Without arguments, s.rsplit() splits s into substrings delimited by any sequence of whitespace and returns the substrings as a list: If is specified, it is used as the delimiter for splitting: (If is specified with a value of None, the string is split delimited by whitespace, just as though had not been specified at all.). Any character value greater than 127 must be specified using an appropriate escape sequence: The 'r' prefix may be used on a bytes literal to disable processing of escape sequences, as with strings: The bytes() function also creates a bytes object.
