Swap the tails of the sequences at positions pos1 and pos2. The tail for pos1 begins at character start1 and the tail for pos2 begins at character start2. It is an error if the value of the start position is greater than the length of the sequence or less than zero. If the length of a sequence is n, the start position may be n, meaning that the tail of the other sequence is appended (python)
