Nested tuples

A nested tuple can be easily unpacked.

buried_treasure = [('Gold plate', 1145, (34.501, -45.234)), 
                   ('Sword', 1156, (34.545, -45.101)), 
                   ('Ring', 1323, (34.547, -45.044))]
for _, year, (lat, long) in buried_treasure:
    print('AD', year, ':', lat, long)
AD 1145 : 34.501 -45.234
AD 1156 : 34.545 -45.101
AD 1323 : 34.547 -45.044
