现有元组t = (0, [1, 2])，使用下标访问其中的数字1的方法是t[m][n]，此处m= ;n= 。
举一反三

- 设A=ξηT，ξ=[1，-2，1]T，η[2，1，1]T，则(E+A)n=______．
- 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]
- t=[1,2,3,4]t[1:2]=[5]则t的结果为（ ） A: [1,5,3,4] B: [1，5，2，3，4] C: [1，2，3，4] D: [5,2,3,4]
- 下面代码的输出结果是li = ["hello",'se',[["m","n"],["h","kelly"],'all'],123,446]print(li[2][1][1]) A: ｎ B: ｈ C: ｍ D: kelly
