4. List of Tuples Given a list of non-empty tuples, return a list sorted in increasing order by the last element in each tuple For example: , 7), (1, 3), (3, 4, 5), (2, 2)] yields [ (2, 2), (1, 3), (3, 4, 5), (1, 7)1 In : def sort_tuple_list(tuple_list): Function to sort a list of non-empty tuples in increasing order by the last element in each tuple ### BEGIN SOLUTION ### END SOLUTION In from nose.tools import assert equal assert_equal (sort_tuple list([(1, 3), (3, 2), (2, 1)), [ (2, 1), (3, 2), (1, 3)]) assert_equal ( sort tuple-list ([ (2, 3), (1, ), (3, 2)j), [(1, 1), (3, 2), (2. 3) assert-equal ( sort tuple-list ([(1, 7), (1, 3), (3, 4, 5), (2, 2)", t(2, 2), (1, 3 .. 4, 5
