Не могу сообразить, как сделать. Задача легкая, но то ли пересидела, то ли мозгов не хватает, не могу решить. Дан список:
[[['A', 0, 0, 3], ['A', 10, 0, 3], ['A', 19, 0, 3], ['A', 23, 0, 2], ['A', 25, 0, 1], ['A', 27, 5, 1]], [['C', 0, 0, 3], ['C', 13, 0, 3], ['C', 27, 5, 3]], [['C', 0, 0, 3], ['C', 11, 5, 3], ['C', 20, 5, 3], ['C', 26, 5, 2]], [['C', 0, 0, 3], ['C', 8, 5, 3], ['C', 21, 5, 3], ['C', 27, 5, 2]], [['A', 0, 0, 3], ['A', 9, 5, 3], ['A', 22, 5, 3], ['A', 28, 5, 2]], [['C', 0, 0, 3], ['C', 11, 5, 3], ['C', 19, 5, 3], ['C', 29, 5, 2]], [['A', 0, 0, 3], ['A', 11, 5, 3], ['A', 23, 5, 3], ['A', 26, 5, 1]], [['C', 0, 0, 3], ['C', 13, 5, 3], ['C', 25, 5, 3], ['C', 28, 5, 2]], [['A', 0, 0, 3], ['A', 13, 5, 3], ['A', 22, 5, 3], ['A', 31, 0, 2]], [['A', 0, 0, 3], ['A', 14, 0, 3], ['A', 24, 0, 3], ['A', 34, 0, 1]]]
Звучит не очень, но вот что мне нужно получить из вышеупомянутого списка:
[[['A', 0, 0, 3], ['A', 10, 0, 3], ['A', 19, 0, 2], ['A', 23, 0, 1], ['A', 25, 0, 1], ['A', 27, 5, 0]], [['C', 0, 0, 3], ['C', 13, 0, 3], ['C', 27, 5, 0]], [['C', 0, 0, 3], ['C', 11, 5, 3], ['C', 20, 5, 2], ['C', 26, 5, 0]], [['C', 0, 0, 3], ['C', 8, 5, 3], ['C', 21, 5, 2], ['C', 27, 5, 0]], [['A', 0, 0, 3], ['A', 9, 5, 3], ['A', 22, 5, 2], ['A', 28, 5, 0]], [['C', 0, 0, 3], ['C', 11, 5, 3], ['C', 19, 5, 2], ['C', 29, 5, 0]], [['A', 0, 0, 3], ['A', 11, 5, 3], ['A', 23, 5, 1], ['A', 26, 5, 0]], [['C', 0, 0, 3], ['C', 13, 5, 3], ['C', 25, 5, 2], ['C', 28, 5, 0]], [['A', 0, 0, 3], ['A', 13, 5, 3], ['A', 22, 5, 2], ['A', 31, 0, 0]], [['A', 0, 0, 3], ['A', 14, 0, 3], ['A', 24, 0, 1], ['A', 34, 0, 0]]]
Буду очень признательна за помощь!
