python并行迭代
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 == '--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.startswith('--expected'):
16 expected = sys.argv
17 elif sys.argv.startswith('--result'):
18 result = sys.argv
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)
