下面代码的输出结果是 a
= [9,6,4,5] N
= len(a) for
i in range(int(len(a) / 2)): a[i],a[N-i-1]
= a[N-i-1],a[i] print(a)[/i][/i]
A: [9,6,5,4]
B: [5,6,9,4]
C: [5,4,6,9]
D: [9,4,6,5]
= [9,6,4,5] N
= len(a) for
i in range(int(len(a) / 2)): a[i],a[N-i-1]
= a[N-i-1],a[i] print(a)[/i][/i]
A: [9,6,5,4]
B: [5,6,9,4]
C: [5,4,6,9]
D: [9,4,6,5]
举一反三
- 下面代码的输出结果是(<br/>) a = [9,6,4,5] N = len(a) for i in range(int(len(a) / 2)):<br/>a[i],a[N-i-1] = a[N-i-1],a[i] print(a)[/i][/i] A: [5,4,6,9] B: [5,6,9,4] C: [9,6,5,4] D: [4,5,6,9]
- 以下程序的输出结果是___________。for i in range(1,11): print(i, end = " ") A: 1 2 3 4 5 6 7 8 9 B: 1 2 3 4 5 6 7 8 9 10 C: 1 2 3 4 5 D: 1 3 5 7 9
- 以下程序的输出结果是（ ）。 frame<br/>= [[1,2,3],[4,5,6],[7,8,9]] rgb<br/>= frame[: : -1] print(rgb) A: [[1,<br/>2, 3], [4, 5, 6]] B: [[7,<br/>8, 9], [4, 5, 6], [1, 2, 3]] C: [[1,2,3],[4,5,6],[7,8,9]] D: [[7,<br/>8, 9]]
- 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]]
- 以下程序的输出结果是:[br][/br]frame = [[1,2,3],[4,5,6],[7,8,9]][br][/br]rgb = frame[::-1][br][/br]print(rgb) A: [[1, 2, 3], [4, 5, 6]] B: [[7, 8, 9]] C: [[1,2,3],[4,5,6],[7,8,9]] D: [[7, 8, 9], [4, 5, 6], [1, 2, 3]]
