描述

Starting with the “n-th” element of the tuple TupleTupleTupleTupletupletuple, tuple_last_ntuple_last_nTupleLastNTupleLastNTupleLastNtuple_last_n selects every element of TupleTupleTupleTupletupletuple and returns it with SelectedSelectedSelectedSelectedselectedselected. Thus, SelectedSelectedSelectedSelectedselectedselected contains all elements of TupleTupleTupleTupletupletuple from index “n” up to the last element of TupleTupleTupleTupletupletuple (including the element at position “n”). The index “n” is determined by the input parameter IndexIndexIndexIndexindexindex. Thus, IndexIndexIndexIndexindexindex must contain a single integer value (if IndexIndexIndexIndexindexindex consists of a floating point number, this must represent an integer value without fraction). Indices of tuple elements start at 0, that means, the first tuple element has got the index 0.

例外：空输入元组

If TupleTupleTupleTupletupletuple is empty, an exception is raised.
