[D]python 文本读出的问题
文本里面的内容如下：

JrId: 1
JournalTitle: AADE editors' journal
MedAbbr: AADE Ed J
ISSN: 0160-6999
ESSN:
IsoAbbr: AADE Ed J
NlmId: 7708172
JrId: 2
JournalTitle: AANA journal
MedAbbr: AANA J
ISSN: 0094-6354
ESSN:
IsoAbbr: AANA J
NlmId: 0431420
JrId: 3
JournalTitle: AARN news letter
MedAbbr: AARN News Lett
ISSN: 0001-0197
ESSN:
IsoAbbr: AARN News Lett
NlmId: 1251052

上面的文本我想插入到数据库里面，（7行一组）故想生成：
insert into (JrId,JournalTitle,MedAbbr,ISSN,ESSN,IsoAbbr,NlmId) values(%.....)

刚接触python 还不是很熟悉，下面是我写的有问题的：

Python code

#!/usr/bin/pythonj=open('J_Entrez1.txt')while True:    t=j.readline().strip().split(':')    if not t:        break    col,value = t    query = "insert into test (`%s`) values (%s)" %(col,'"'+value+'"')    print queryj.close()

上面得出来的是每一行生成了一条insert：
insert into test (`JrId`) values (" 1")
insert into test (`JournalTitle`) values (" AADE editors' journal")
insert into test (`MedAbbr`) values (" AADE Ed J")
insert into test (`ISSN`) values (" 0160-6999")
insert into test (`ESSN`) values ("")
insert into test (`IsoAbbr`) values (" AADE Ed J")
insert into test (`NlmId`) values (" 7708172")

而我想要的是
insert into (JrId,JournalTitle,MedAbbr,ISSN,ESSN,IsoAbbr,NlmId) values("1"," AADE editors' journal"," AADE Ed J"," 0160-6999",""," AADE Ed J"," 7708172")
…………

想半天还是不知道如何实现。。麻烦高人指点下。

[解决办法]
只要你文本文档格式都是7个一组,这个脚本可以读任意多组

Python code

lines = open('J_Entrez1.txt').readlines()ind = -1cnt = 0for line in lines:    if cnt%7==0:        ind += 1        exec('dic'+str(ind)+'={}')    exec('dic'+str(ind)+'[line.strip().split(":")[0]]=line.strip().split(":")[1].strip()')    cnt += 1for i in range(ind+1):    print '+++++NEW LINE++++++++++++++++++'    first = 'insert into ('    last = ') values('    for key in eval('dic'+str(i)+'.keys()'):        first += key+','        last += '"'+eval('dic'+str(i)+'[key]')+'",'    query = first[:-1]+last[:-1]+')'        print query
[解决办法]
Python code
fin = open('in.txt','r')fout = open('out.txt','w')i=0out = 'insert into ('values = ')values('for line in fin.readlines():    print line    content = line.split(':')    if i % 7 == 6:        out+=content[0].strip()        values+='"' + content[1].strip() + '"'        fout.write(out+values+')\n')        print i        out = 'insert into ('        values = ')values('    else:        out +=content[0].strip()+','        values+='"' + content[1].strip() + '"' + ','    i+=1fin.close()fout.close()
