在用谷歌在搜索技术文章时，总是时不时的打不开网页，于是写了一个python/ target=_blank class=infotextkey>python脚本，感觉用着还行，分享给大家。
注意：win7或者WIn8用户要用管理员权限执行。
项目地址：http://code.google.com/p/my-hosts-file/downloads
复制代码 代码如下:
import urllib
import os
import shutil
hostspath = "C:WindowsSystem32driversetc"
savepath = hostspath + "hostsave"
def download_hosts(url = "http://my-hosts-file.googlecode.com/svn/trunk/hosts"):
os.chdir(hostspath)
if os.getcwd() != hostspath:
print("Switch Dir to System32 Error,check permission!npwd:"+os.getcwd())
exit()
try:
urllib.urlretrieve(url, "hostsave")
except:
print 't Error when retrieveing hosts file from url: ', url
def backup_hosts():
shutil.copy("hosts","hosts.bak")
def replace_hosts():
shutil.copy("hostsave", "hosts")
print("Replace original hosts file finished, then flush dns...")
os.remove(savepath)
os.system("ipconfig /flushdns")
def main():
download_hosts()
backup_hosts()
replace_hosts()
if __name__ == '__main__':
main()
