One possibility is using nested records to fake a tuple. Look at the
attached script for an example. Here is the output of the script:
nested_table:
[(('A', ' ', 0), 0.0) (('B', '!', 1), 1.0) (('C', '"', 2), 4.0)
(('D', '#', 3), 9.0) (('E', '$', 4), 16.0) (('F', '%', 5), 25.0)
(('G', '&', 6), 36.0) (('H', "'", 7), 49.0) (('I', '(', 8), 64.0)
(('J', ')', 9), 81.0)]
nested column:
[('A', ' ', 0) ('B', '!', 1) ('C', '"', 2) ('D', '#', 3) ('E', '$', 4)
('F', '%', 5) ('G', '&', 6) ('H', "'", 7) ('I', '(', 8) ('J', ')', 9)]
Bingo! Key found in row # 3 . Value: 9.0
