并行迭代:同时并行遍历两个列表
for line1,line2 in zip(line1_list, line2_list):
...
无聊,贴一段刚才的代码:
1 import sys
2 import string
3
4 expected=
5 result=
6
7 if sys.argv[1] == --help:
8 print example: --expected=expected --result=result
9 if len(sys.argv) < 3:
10 print please provide correct file path
11 sys.exit()
12
13 index = 1
14 while index < 3:
15 if sys.argv[index].startswith(--expected):
16 expected = sys.argv[index][11:]
17 elif sys.argv[index].startswith(--result):
18 result = sys.argv[index][9:]
19 index += 1
20
21 expected_input = open(expected, r)
22 result_input = open(result, r)
23 expected_lines = expected_input.readlines()
24 result_lines = result_input.readlines()
25 expected_input.close()
26 result_input.close()
27
28 correct = 0
29 wrong = 0
30
31 if len(expected_lines) != len(result_lines):
32 print line counts are not consistent
33 else:
34 for exp, res in zip(expected_lines, result_lines):
35 if exp == res:
36 correct += 1
37 else:
38 wrong += 1
39
40 accuracy = float(correct) / (correct + wrong)
41 print All: + str(correct + wrong) + Correct: + str(correct);
42 print Accuracy = + str(accuracy)
彼此相爱,却不要让爱成了束缚:不如让它成为涌动的大海,两岸乃是你们的灵魂。互斟满杯,却不要同饮一杯。相赠面包,却不要共食一个。一起歌舞欢喜,却依然各自独立,相互交心,却不是让对方收藏。因为唯有生命之手,方能收容你们的心。站在一起却不要过于靠近。—— 纪伯伦《先知》
