Make the left-hand side an empty slice: >>> words = ["x1", "x2", "x3", "x4", "x5"] >>> w = words[-2:] >>> del words[-2:] >>> words[2:2] = w >>> words ['x1', 'x2', 'x4', 'x5', 'x3'] Or note that the operation is equivalent to moving the third item to the end: >>> words = ["x1", "x2", "x3", "x4", "x5"] >>> words.append(words.pop(2)) >>> words ['x1', 'x2', 'x4', 'x5', 'x3'] -- https://mail.python.org/mailman/listinfo/python-list
