已知列表m=[[1,2],[3,4]]，有列表a=[[row[i] for row in m] for i in range(2)]，则a[0][1]是[/i]

假设数据在A1:A10单元格,如果想在B列直接从小到大显示排序结果则可以用这个公式()向下复制即可。(1.0) A: =SMALL($A$1:A$10,ROW(2:2)) B: =SMALL($A$1:$A$10,ROW(1:1)) C: =SMALL($A$1:$A$10,ROW(0:0)) D: =SMALL($A1:$A$10,ROW(1:1))

下面程序运行后输出是_______。a = [1, 2, 3, 4, [5, 6], [7, 8, 9]]s = 0for row in a: if type(row)==list: for elem in row: s += elem else: s+=rowprint(s)
