Question

我有一个大的Expect脚本输出文件，其中包含设备列表及其TACACS服务器IP地址。

我想遍历该文件，并为每个设备确定它是否得到：只有新的TACACS IP地址;或新旧;或者，都没有。（旧的只是不可能的，因为我在所有设备上添加了新功能;但是，包括未来的要求会很好......）

对于＆＃34;安全＆＃34;我用虚拟数据替换了实际的设备名称和IP地址。此外，＆＃34;打印＆＃34;取代＆＃34;写＆＃34;的陈述声明只是故障排除的遗留物。

Here is the script:

 #!/usr/bin/python

 import re

#####################################################

new1 = "tacacs-server host 1.1.1.1"
new2 = "tacacs-server host 2.2.2.2"
new1_in_block = 0
new2_in_block = 0

has_new_ip = 0

#####################################################
  old1 = "tacacs-server host 2.2.2.2" 
  old2 = "tacacs-server host 3.3.3.3" 
  old3 = "tacacs-server host 4.4.4.4"
  old4 = "tacacs-server host 5.5.5.5"
  old5 = "tacacs-server host 6.6.6.6"
  old6 = "tacacs-server host 7.7.7.7"

 has_old_ip = 0

＃

 tacacs_servers = open ("test_block3.txt","r+")

＃

complete =  open  ("complete_output.txt","r+")

＃

 not_complete =  open  ("not_complete_output.txt","r+")

######################################################

not_checked = open ("not_checked.txt","r+")

#####################################################

 for line in tacacs_servers:

 if 'show' in line:
  DeviceName = (re.search(".*#",line).group())
  DeviceName = DeviceName.replace('#',' ')

 if 'show' not in line:

  if str(new1) or str(new2) in line:
   has_new_ip = 1

  elif str(new1) or str(new2) not in line:
   has_new_ip = 0

 if 'spawn' in line:
  if has_new_ip == 0:
   print (DeviceName)
   print ("NOT COMPLETE\n")

  elif has_new_ip == 1:
   print (DeviceName)
   print ("COMPLETE\n")


 new1= new2 = has_new_ip = 0
 old1 = old2 = old3 = old4 = old5 = old6 = has_old_ip = 0

    Here is test_block3.txt:


    ABC-DEF#show run | include tacacs-server host
    tacacs-server host 1.1.1.1
    GHI-JKL#spawn ssh -q user@MN-OPQ


    MN-OPQ#show run | include tacacs-server host
    tacacs-server host 1.1.1.1
    tacacs-server host 3.3.3.3
    tacacs-server host 2.2.2.2
    MN-OPQ# #spawn ssh -q user@AZXY-123

    AZXY-123# show run | include tacacs-server host
    AZXY-123# spawn ssh -q  user@P44AR-1212



  Here is the current Python Script output:

  ABC-DEF 
  COMPLETE

  MN-OPQ 
  COMPLETE

  AZXY-123 
  COMPLETE

当然不是最优雅的方式，但是：

import re

f=open('list.txt','r')

devices_list={}
device_name=None

old_ip_list=['1.1.1.1','2.2.2.2']
new_ip_list=['3.3.3.3']

for line in f:
    match=re.search('^(.*)\s*#\s*show\s+run',line)
    if match!=None:
        device_name=match.groups()[0].strip()
        devices_list[device_name]=[]
        continue
    match=re.search('tacacs-server\s+host\s+(\S+)',line)
    if match!=None:
        host=match.groups()[0].strip()
        devices_list[device_name].append(host)


print devices_list

devices_list_new={}
new_list=[]
old_list=[]
both_list=[]
neither_list=[]

for device in devices_list.keys():
    devices_list_new[device]=[]
    for ip in devices_list[device]:
        if ip in old_ip_list:
            devices_list_new[device].append('old')
        elif ip in new_ip_list:
            devices_list_new[device].append('new')


for device in devices_list_new.keys():
    if 'old' in devices_list_new[device] and 'new' in devices_list_new[device]:
        both_list.append(device)
    elif 'new' in devices_list_new[device]:
        new_list.append(device)
    elif 'old' in devices_list_new[device]:
        old_list.append(device)
    else:
        neither_list.append(device)

print 'New:'
for device in new_list:
    print device

print 'Old:'
for device in old_list:
    print device

print 'Both:'
for device in both_list:
    print device

print 'Neither:'
for device in neither_list:
    print device
