python列表纯大于零从小到大的整数，连续的数归一组，怎么划分？

python列表[1,2,4,6,7,8,9,12,15]分成[1,2],[4],[6,7,8,9],[12],[15]

Answer 1

list = [1,2,4,6,7,8,9,12,15]

result = [[list[0]], ]
for n in list[1:]:
    if n == result[-1][-1] + 1:
        result[-1].append(n)
    else:
        result.append([n])

print(result)

输出：[[1, 2], [4], [6, 7, 8, 9], [12], [15]]
