源代码如下：

#coding=gbkimport urllib,reimport os,sysfrom bs4 import BeautifulSoup as soupdef get_ip(ip):    a = []    url = "http://www.ip138.com/ips138.asp?ip={0}&action=2".format(ip)    opurl = urllib.urlopen(url)    o_data = opurl.read()    opurl.close()    c = soup(o_data)    data = c.find_all("table",{"width":"80%"})    for x in  data:        x_l = ''.join(re.findall(u'本站主数据：(.*)',x.li.text))        return  '    %s  %s \n' % (ip,x_l)       def get_tracert(domain):    ip_list = []    data = os.popen('tracert -d %s ' % domain).readlines()    b = re.compile(r'(\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3})')    data = [  b.findall(x) for x in data ]    for x in data:        if x != []:            ip_list.append(''.join(x))    return ip_listif __name__ == '__main__':    print '访问%s 经过的路由如下：\n' % sys.argv[1]    for x in get_tracert(sys.argv[1]):        print get_ip(x)

保存成tracert.py

执行结果如下：
