复制代码 代码如下:

import os
import sys
import pickle
import string
import re
import time
from datetime  import date
from csv_timestamp_datetime import *

 
ip_region_list = pickle.load(open('ip_region_list.pickle','r'))

            return ip_region_list[middle][2]
        else:
            if ip_region_list[middle][0] >= key:
                end = middle - 1
            else:
                begin = middle + 1
