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]
A: [2, 4, 8,16]
B: [2, 4, 6, 8]
C: [1, 2, 4, 8]
D: [0, 2, 4, 6]
举一反三
- 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}
- “[ 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]
- 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
- 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]
