我需要一些python脚本的帮助.我需要在dhcpd文件中搜索主机entires,它们的MAC和IP,并将它打印在一行中.我能够找到主机名和IP地址,但无法弄清楚如何从if语句中获取变量以放入一行.有任何建议,代码如下:

#!/usr/bin/python

import sys
import re

#check for arguments

if len(sys.argv) > 1:
    print "usage: no arguments required"
    sys.exit()
else:
    dhcp_file = open("/etc/dhcp/dhcpd.conf","r")
    for line in dhcp_file:
        if re.search(r'\bhost\b',line):
            split = re.split(r'\s+', line)
            print split[1]
        if re.search(r'\bhardware ethernet\b',line):
            ip = re.split(r'\s+',line)
            print ip[2]
    dhcp_file.close()
