统计程序，前面两道题分别有3个和2个选项，单选。后面两道题均有6个选项，多选。
统计每道题选择a，b，c，d的百分比。很简单的需求。实现如下(发现python中没有自加操作符)：
1 def calc():
2
3 file = open('C:\\wiki-query2.txt','r')
4 content = file.read()
5 import re
6 entries = re.split('\n+',content)
7 for entry in entries:
8 if(len(entry) == 0 ):
9 break
10 #print(entry)
11 words = (re.split('\t',entry))
12 #words = (str(words)).strip()
13 #print(words[0]+","+words[4])
14 checkSingleChoice(words[4],answer1)
15 checkSingleChoice(words[5],answer2)
16 checkMuliChoice(words[6],answer3)
17 checkMuliChoice(words[7],answer4)
18
19 file.close()
20 print(answer1)
21 print(answer2)
22 print(answer3)
23 print(answer4)
24 print('the results are:')
25 calPercent(answer1,1)
26 calPercent(answer2,2)
27 calPercent(answer3,3)
28 calPercent(answer4,4)
29
30
31
32 def checkSingleChoice(item, answer):
33 if item == 'a':
34 answer[0] = answer[0]+1
35 elif item =='b':
36 answer[1]= answer[1]+1
37 elif item =='c':
38 answer[2]= answer[2]+1
39 else:
40 answer[3]= answer[3]+1
41
42 def checkMuliChoice(item, answer):
43 if 'a' in item:
44 answer[0] = answer[0]+1
45 if 'b' in item:
46 answer[1]= answer[1]+1
47 if 'c' in item:
48 answer[2]= answer[2]+1
49 if 'd' in item:
50 answer[3]= answer[3]+1
51 if 'e' in item:
52 answer[4]= answer[4]+1
53 if 'f' in item:
54 answer[5]= answer[5]+1

[12, 6, 13, 6, 2, 1]
[1, 12, 12, 7, 2, 2]
the results are:
Q[1]:

Q[2]:

Q[3]:

choice[a] :2.78%, choice[b] :33.33%, choice[c] :33.33%, choice[b] :19.44%, choice[e] :5.56%, choice[f] :5.56%,
其中，在统计函数的显示百分比方法中，要设置print结果显示的小数位数，花了些时间找方法，结果：
print(':%.2f' %(p)+'%',end=', ')，f表示小数点为是，g表示有效数字位数，e为科学技计数法。
