set1 = {x for x in range(10) if x%2==0} print(set1) 以上代码的运行结果为？
A: {0, 2, 4, 6}
B: {2, 4, 6, 8}
C: {0, 2, 4, 6, 8}
D: {4, 6, 8}
A: {0, 2, 4, 6}
B: {2, 4, 6, 8}
C: {0, 2, 4, 6, 8}
D: {4, 6, 8}
举一反三
- 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}
- 若有a = [2*x for x in range(4)]，语句print(a)输出为 A: [2, 4, 8,16] B: [2, 4, 6, 8] C: [1, 2, 4, 8] D: [0, 2, 4, 6]
- 以下代码的输出结果是（）for i in range(0,10,2): print(i,end="") A: 0 2 4 6 8 B: 2 4 6 8 C: 0 2 4 6 8 10 D: 2 4 6 8 10
- “[ 2*x+2 for x in range(5) ]”生成的列表是（ ）。 A: [2, 4, 6, 8, 10] B: [0, 2, 4, 6, 8] C: [1, 2, 3, 4, 5] D: [0, 1, 2, 3, 4]
- >>>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']
