python wrong file format cause unpack error -

when use python code below deal right.txt , wrong.txt, though totally same, wrong.txt cannot run. indent problem?

my code here:

import re if __name__ == '__main__':     open('wrong.txt') fin:         text = fin.read()     l = [p p in text.split('\nsentence #') if p]     p in l:         lines, deps = tuple(p.split('\n\n')[:2]) 

right.txt:

sentence #1 (33 tokens): introduction. [text=. characteroffsetbegin=208 characteroffsetend=209 partofspeech=. lemma=.]  (root     (. .)))  root(root-0, stored-18) 

wrong.txt:

sentence #1 (33 tokens): introduction. [text=. characteroffsetbegin=208 characteroffsetend=209 partofspeech=. lemma=.]  (root      (. .)))  root(root-0, stored-18) 

i had compare of 2 txt files, , found (4111)differeces line endings (new line). right.txt uses (0x0a, '\n'); wrong.txt uses (0x0d0a, '\r\n').

with above in mind, code this:

import re if __name__ == '__main__':     open('wrong.txt') fin:         text = fin.read()     ending = '\r\n' if '\r\n' in text else '\n'     l = [p p in text.split( ending + 'sentence #') if p]     p in l:         lines, deps = tuple(p.split( ending * 2 )[:2])
