在Python中创建自定义迭代器以搜索大型数据集中的子列表

class SublistIterator:
    def __init__(self, data, sublist_length):
        self.data = data
        self.sublist_length = sublist_length
        self.current_index = 0

    def __iter__(self):
        return self

    def __next__(self):
        if self.current_index + self.sublist_length <= len(self.data):
            sublist = self.data[self.current_index:self.current_index + self.sublist_length]
            self.current_index += 1
            return sublist
        else:
            raise StopIteration

# 示例用法
data = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
sublist_length = 3

iterator = SublistIterator(data, sublist_length)
for sublist in iterator:
    print(sublist)
