所以我在写下面的代码。当我的孩子参考文件.txt有多行。但当我的孩子参考文件.txt文件只有一行。为什么?我还想知道为什么我的代码不运行代码的“try”部分,但它总是只运行“exception”部分。你知道吗
但是,这段代码对我的“try:”部分没有任何作用
import sys
import urllib2
from lxml import etree
import os
getReference = open('Reff.txt','r') #open the file that contains list of reference ids
global tID
for tID in getReference:
tID = tID.strip()
try:
with open(''+tID.strip()+'.txt') as f: pass
fileInput = open(''+tID+'.txt','r')
readAA = fileInput.read()
store_value = (readAA.partition('\n'))
aaSequence = store_value[2].replace('\n', '') #concatenate lines
makeList = list(aaSequence)#print makeList
inRange = ''
fileAddress = '/database/int/data/'+tID+'.txt'
filename = open(fileAddress,'r')#name of the working file
print fileAddress
with open(fileAddress,'rb') as f:
root = etree.parse(f)
for lcn in root.xpath("/protein/match[@dbname='PFAM']/lcn"):#find dbname =PFAM
start = int(lcn.get("start"))#if it is PFAM then look for start value
end = int(lcn.get("end"))#if it is PFAM then also look for end value
while start <= end:
inRange = makeList[start]
start += 1
print outputFile.write(inRange)
outputFile.close()
break
break
break
except IOError as e:
newURL ='http://www.uniprot.org/uniprot/'+tID+'.fasta'
print newURL
response = urllib2.urlopen(''+newURL) #go to the website and grab the information
creatNew = open(''+uniprotID+'.txt','w')
html = response.read() #read file
creatNew.write(html)
creatNew.close()
所以,当你尝试/除外-如果尝试失败,除外运行。除了总是在运行,因为尝试总是失败的。你知道吗
最可能的原因是你有这个“印刷品”outputFile.write文件(inRange)”,但您以前没有声明outputFile。你知道吗
ETA:而且,看起来您只对测试for循环的第一次通过感兴趣?你在那一点上就断了。在这种情况下,你的其他休息时间是无关的,因为当那个休息时间在那里的时候,他们永远不会到达。你知道吗
