web采集的数据为 %u6B63%u5F0F%u4EBA%u5458,需要读取并转换为python对象,想了下不调用Javascript去eval,只能自己翻译了。

核心代码:

import re
import codecs
pattern = re.compile('%u[0-9A-Z]{4}')

n = codecs.open('d:\\new.txt', 'w', 'utf-8') 
with open('d:\\p', 'r') as f:
 for l in f:
  for i in pattern.findall(l):
   l = l.replace(i, unichr(int(i[2:], 16)))
   n.write(l)

n.close()
Copy after login
