Windows下生成txt文件时的换行

import sys
import os
import string
import re

def replace(file_name):

line_list = file.readlines()
new_line_list = []
pattern = re.compile('"(.*)"')
index = 0
while index <len(line_list):
line = line_list[index]
index += 1

kaValue = pattern.findall(line);
if len(kaValue) > 0:
line = pattern.findall(line)[0] + "\n"
else:
line = ""
new_line_list.append(line)
new_file = open("埋点.txt","wb")
new_file.writelines(new_line_list)

if __name__ == '__main__':
replace("DIYActionConstant.as")
