- 下列哪条语句是正确的( ) A: A=[1 2;3 4];B=[3;7];A.*B; B: A=cell(2,3);A(1,2)=[4;5]; C: A=[2 3 5 7;9 4 6 1;7 3 2 5];B=[1 7;0 5];A(2:end,2:2:end) D: x=-5:5;y=-5:5;z=x.*x-y.*y;surf(x,y,z);
- >>>x= [10, 6, 0, 1, 7, 4, 3, 2, 8, 5, 9]>>>print(x.sort()) 语句运行结果正确的是( )。 A: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10] B: [10, 6, 0, 1, 7, 4, 3, 2, 8, 5, 9] C: [10, 9, 8, 7, 6, 5, 4, 3, 2, 1, 0] D: ['2', '4', '0', '6', '10', '7', '8', '3', '9', '1', '5']
- set1 = {x for x in range(10) if x%2!=0} print(set1) 以上代码的运行结果为? A: {1, 3, 5, 7, 9} B: {1, 3, 5, 7} C: {3, 5, 7, 9} D: {3, 5, 7}
