描述

tuple_inserttuple_insertTupleInsertTupleInsertTupleInserttuple_insert inserts the elements of the tuple InsertTupleInsertTupleInsertTupleInsertTupleinsertTupleinsert_tuple at index into the tuple TupleTupleTupleTupletupletuple and returns them in the tuple ExtendedExtendedExtendedExtendedextendedextended. In this context IndexIndexIndexIndexindexindex determines the start index of the elements and InsertTupleInsertTupleInsertTupleInsertTupleinsertTupleinsert_tuple the values to insert. Successive values of TupleTupleTupleTupletupletuple will be positioned after the inserted values of InsertTupleInsertTupleInsertTupleInsertTupleinsertTupleinsert_tuple. The parameter IndexIndexIndexIndexindexindex must contain a single integer value (any floating point number must represent an integer value without fraction). Indices of tuple elements start at 0. Therefore, the first tuple element has got the index 0. If IndexIndexIndexIndexindexindex contains the length of TupleTupleTupleTupletupletuple as index, InsertTupleInsertTupleInsertTupleInsertTupleinsertTupleinsert_tuple will be appended. The length of the result tuple ExtendedExtendedExtendedExtendedextendedextended is always the sum of the two input tuples TupleTupleTupleTupletupletuple and InsertTupleInsertTupleInsertTupleInsertTupleinsertTupleinsert_tuple. For example, if TupleTupleTupleTupletupletuple contains the values [0,1,0,1,0,1], the IndexIndexIndexIndexindexindex contains the value [3] and the InsertTupleInsertTupleInsertTupleInsertTupleinsertTupleinsert_tuple contains the values [2,2,2], then the output tuple ExtendedExtendedExtendedExtendedextendedextended will contain the values [0,1,0,2,2,2,1,0,1]. It is allowed to mix strings and numbers in the input tuples TupleTupleTupleTupletupletuple and InsertTupleInsertTupleInsertTupleInsertTupleinsertTupleinsert_tuple。

例外：空输入元组

If any of the input tuples is empty, an exception is raised.
