先放代码：

#!/usr/bin/python2.7
#coding:utf8

path = '/home/python_learning/nickname.list'

with open(path) as fin:
  for line in fin.readlines():
     print line.decode('string-escape')

'/home/python_learning/nickname.list'内容大约是：

\346\261\237\350\245\277\347\224\265\344\277\241
\345\271\277\345\217\221\351\223\266\350\241\214

真没想到用string-escape转为文字啊
