举一反三
- >>>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)} 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}
- 如下代码运行后的输出结果是()。 ls = list(range(6)) ls.append(8) print(ls) A: [1, 2, 3, 4, 5, 6, 8] B: [0, 1, 2, 3, 4, 5, 8] C: [8, 1, 2, 3, 4, 5, 6] D: [8, 0, 1, 2, 3, 4, 5]
- 利用行列式的性质计算下列行列式的值1 2 0 0 02 5 0 0 0 9 8 1 2 37 6 4 5 65 4 7 8 9
- 已知x(n)={1, 2, 3},y(n)={1, 2, 1},则x(n)*y(n)=________。(下划线表示n=0) A: {1, 4, 8, 8, 3} B: {1, 4, 8, 8, 3} C: {1, 4, 8, 8, 3} D: {1, 4, 8, 8, 3}
