[FIXED] Print results from multiple "if" statements in one line

Issue

I need to search a dhcpd file for host entires, their MAC and IP, and print it in one line. I am able to locate the hostname and IP address but cannot figure out how to get the variables out of the if statement to put in one line.

The code is below:

#!/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()

Solution

There are a number of ways that you could go about this. The simplest is probably to initialize an empty string before the if statements. Then, instead of printing split[1] and ip[2], concatenate them to the empty string and print that afterwards. So it would look something like this:

    printstr = ""
    if re.search...
        ...
        printstr += "Label for first item " + split[1] + ", "
    if re.search...
        ...
        printstr += "Label for second item " + ip[2]
    print printstr
