数组的子序列不为零

连续的子序列？寻呼Groupby博士，博士

itertools.groupby

>>> from itertools import groupby>>> l = [240,200,160,4,0,0,0,0,4,4,4,0,0,0,1,1,1,1]>>> [list(g) for k,g in groupby(l, lambda x: x != 0) if k][[240, 200, 160, 4], [4, 4, 4], [1, 1, 1, 1]]

甚至我们利用事实

bool(0)

False

bool(any other integer)

True

>>> [list(g) for k,g in groupby(l, bool) if k][[240, 200, 160, 4], [4, 4, 4], [1, 1, 1, 1]]
