如下程序的输出结果是:L1 =[‘abc’, [‘123’,‘456’]]L2 = [‘1’,‘2’,‘3’]print(L1 >; L2)
A: False
B: TypeError: ‘>;’ not supported between instances of ‘list’ and ‘str’
C: 1
D: True
A: False
B: TypeError: ‘>;’ not supported between instances of ‘list’ and ‘str’
C: 1
D: True
举一反三
- 以下程序的输出结果是: L1 =['abc', ['123','456']] L2 = ['1','2','3'] print(L1 > L2) A: TypeError: '>' not supported between instances of 'list' and 'str' B: False C: True D: 1
- 以下代码的输出结果是（_____）。L1 =['abc', ['123','456']] L2 = ['1','2','3'] print(L1 > L2) A: False B: True C: TypeError: '>' not supported between instances of 'list' and 'str' D: 1
- 以下程序的输出结果是()。L1=[1,2,3,4] L2 = L1. copy() L2.reverse() print(L1) A: 1,2,3,4 B: [4,3,2, 1] C: [1,2, 3,4] D: 4,3,2, 1
- 以下程序的输出结果是： L2 = [1,2,3,4] L3 = L2.reverse() print( L3) A: [1,2,3,] B: [3, 2, 1] C: None D: [4, 3, 2, 1]
- 两根受拉杆件，若材料相同，受力相同，L1=2L2，A1=2 A2，则两杆的伸长△L和轴向线应变ε的关系为（ ） A: △L1=△L2，ε1=ε2 B: △L1=△L2，2ε1=ε2 C: △L1=2△L2，ε1=ε2 D: △L1=2△L2，ε1=2ε2
