win7以上需要使用管理员权限操作。
复制代码 代码如下:
# -*- coding: utf-8 -*-
import os
import glob
import shutildef format_file_list(files):
        all_files_str =
        for i in range(len(files)):
                all_files_str +=  str(i)+:+files[i]+\n
        return all_files_str
hosts_path = c:\\windows\\system32\\drivers\\etc
files =  os.listdir(hosts_path)
os.chdir(hosts_path)
if os.getcwd() != hosts_path:
        print(switch dir to system32 error,check permission!\npwd:+os.getcwd())
        exit()
hosts_files = glob.glob(host*)
choosed_file_idx = int(input(choose hosts file index:\n+format_file_list(hosts_files)))
files_num = len(hosts_files)
if (choosed_file_idx = files_num) :
        print(please choose a file in the lists!)
        exit()
print(choosed idx:{0},file:{1}..format(choosed_file_idx,hosts_files[choosed_file_idx]))
shutil.copy(hosts,hosts.bak)
shutil.copy(hosts_files[choosed_file_idx],hosts)
print(copy ok,then flush dns...)
os.system(ipconfig /flushdns)
