举一反三
- 如果 frame = [[1,2,3],[4,5,6],[7,8,9]],则rgb = frame[::-1]的值是: A: [[7, 8, 9]] B: [[1,2,3],[4,5,6],[7,8,9]] C: [[7, 8, 9], [4, 5, 6], [1, 2, 3]] D: [[1, 2, 3], [4, 5, 6]]
- 以下程序的输出结果是: frame = [[1,2,3],[4,5,6],[7,8,9]] rgb = frame[::-1] print(rgb) A: [[7, 8, 9]] B: [[1,2,3],[4,5,6],[7,8,9]] C: [[7, 8, 9], [4, 5, 6], [1, 2, 3]] D: [[1, 2, 3], [4, 5, 6]]
- 以下程序的输出结果是:( )。frame = [[1,2,3],[4,5,6],[7,8,9]]rgb = frame[::-1]print(rgb) A: [[1,2,3],[4,5,6],[7,8,9]] B: [[1, 2, 3], [4, 5, 6]] C: [[7, 8, 9], [4, 5, 6], [1, 2, 3]] D: [[7, 8, 9]]
- 下列语句执行后,D的值为()。A=[1:3,7;4:6,-56;34,23,56,-45;4,2,4,5];D=max([A(3),A(6),A(8),A(11)]) A: 34 B: 5 C: 2 D: 56
- 以下程序的输出结果是:<br/>frame<br/>= [[1,2,3],[4,5,6],[7,8,9]]; rgb<br/>= frame[::-1]; print(rgb) A: [[7, 8, 9], [4, 5, 6], [1, 2, 3]] B: [[1, 2, 3], [4, 5, 6]] C: [[7, 8, 9]] D: [[1,2,3],[4,5,6],[7,8,9]]
