我需要有關(guān)python腳本的一些幫助。我需要在dhcpd文件中搜索主機(jī)整體，其MAC和IP，并將其打印在一行中。我能夠找到主機(jī)名和IP地址，但無法弄清楚如何將if語句中的變量放入一行中。任何建議，代碼如下：#!/usr/bin/pythonimport sysimport re#check for argumentsif 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()

您可以通過多種方法進(jìn)行此操作。最簡(jiǎn)單的方法可能是在if語句之前初始化一個(gè)空字符串。然后，不要打印split [1]和ip [2]，而是將它們連接到空字符串，然后打印。所以看起來像這樣：
printstr = ""
if re.search...
...
printstr += "Label for first item " + split[1] + ", "
if re.search...
...
printstr += "Label for second item " + ip[2]
print printstr

您還可以使用標(biāo)記curhost，并填充字典：
with open("dhcpd.conf","r") as dhcp_file:
curhost,hosts=None,{}
for line in dhcp_file:
if curhost and '}' in line: curhost=None
if not curhost and re.search(r'^\s*host\b',line):
curhost=re.split(r'\s+', line)[1]
hosts[curhost] = dict()
if curhost and 'hardware ethernet' in line:
hosts[curhost]['ethernet'] = line.split()[-1]
print hosts
