      >>>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']

      下列数组声明语句中,不正确的是_________。 A: Dim a(9) As Single = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10} B: Dim a() = {1, 2, 3, 4, 5, 6, 10} C: Dim a( ,) As Single = {{1, 2, 3, 4, 5}, {6, 7, 8, 9, 10}} D: Dim a() As Single = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10} E: Dim n As Integer=10Dim a(n) As Single

      set1 = {x for x in range(10)} print(set1) 以上代码的运行结果为? A: {0, 1, 2, 3, 4, 5, 6, 7, 8, 9} B: {0, 1, 2, 3, 4, 5, 6, 7, 8, 9,10} C: {1, 2, 3, 4, 5, 6, 7, 8, 9} D: {1, 2, 3, 4, 5, 6, 7, 8, 9,10}

      已知a=[1 2 3; 4 5 6; 7 8 9],执行命令:a([3,1],:)=a([1,3],:),a将变为( )。 A: [4 5 6;4 5 6;4 5 6] B: [7 8 9;4 5 6;1 2 3] C: [2 2 2;5 5 5;8 8 8] D: [3 2 1;6 5 4;9 8 7]
