Google App Engine，Python列表处理-访问列表索引[0] [0]时出错

Question

I'm having an issue on Google App Engine that is pretty weird. I have small text file, its 311kbs. The text inside needs parsed. My code works fine running local, but when I push it out to GAE, it fails. I've shortened it to the below simple example, to show what breaks. The code below fails at writing out what should be in splitlist[0][0], interestingly, if try splitlist[0] it prints out the entire text file.

import webapp2
import os, re

#Load the text file...
file = os.path.join(os.getcwd(), 'TextFileEN.txt')
openfile=open(hymnfile)
text=openfile.read()
#List for split text
splitlist=[]

#Split text on the consistent 4 carriage returns.
textsplit=splitlist.append(text.split('\n\n\n\n'))

class MainPage(webapp2.RequestHandler):
    def get(self):
        self.response.headers['Content-Type'] = 'text/plain'
        self.response.out.write(splitlist[0][0])

app = webapp2.WSGIApplication([('/', MainPage)], debug=True)

This kind of pattern is created by the splitlist.append(text.split()) command [["item1", "item2", "item3",]] when I run it local, and I can access the item like this splitlist[0][0] gives me "item1". I've tried this with Python25 and Python27 on app engine, and when deployed it fails as described above. Any ideas?

Answer 1

Is it possible that something happened to your text file when uploading?

It looks like split is not recognizing the '\\n\\n\\n\\n'.
