CiscoConfigParser 和函数

Question

我正在努力使代码更清晰、更易于管理，我想从读取一个 cisco 文件开始。但是，当我尝试将它放入函数中时，它无法给我输出。同样的功能完全适用于函数

工作模型

parse = CiscoConfParse("C:\python\mydata\TestConfigFile.txt")    
TCPSrv = parse.find_objects("service\stcp\sdestination\seq")
UDPSrv = parse.find_objects("service\sudp\sdestination\seq")
ObjectNetwork = parse.find_objects("^object\snetwork\s")
ObjectGroupSrv = parse.find_objects("^object-group\sservice")
ObjectGroupNetwork = parse.find_objects("^object-group\snetwork\s")

这会为上面的所有内容创建一个列表，就像下面的列表一样

TCPSrv = [<IOSCfgLine # 83 ' service tcp destination eq https' (parent is # 82)>,<IOSCfgLine # 97 ' service tcp destination eq www '(parent is # 102)>]

但是当我把它放到一个函数中时，它不起作用。这是我第一次尝试使用函数，我知道我做错了什么。

这是我的函数代码

def cisco(filename):
    parse = CiscoConfParse(filename)
    TCPSrv = parse.find_objects("service\stcp\sdestination\seq")
    UDPSrv = parse.find_objects("service\sudp\sdestination\seq")
    ObjectNetwork = parse.find_objects("^object\snetwork\s")
    ObjectGroupSrv = parse.find_objects("^object-group\sservice")
    ObjectGroupNetwork = parse.find_objects("^object-group\snetwork\s")
    return TCPSrv, UDPSrv, ObjectNetwork, ObjectGroupSrv, ObjectGroupNetwork


file = C:\python\mydata\TestConfigFile.txt


cisco(file)

这不会给出任何输出。

>>> TCPSrc
Traceback (most recent call last):
  File "<input>", line 1, in <module>
NameError: name 'TCPSrc' is not defined

我也试过这样写在下面

cisco("C:\python\mydata\TestConfigFile.txt")

有人可以帮助我做错什么吗？

Answer 1

This does not give any output

>>> TCPSrc
Traceback (most recent call last):
  File "", line 1, in 
NameError: name 'TCPSrc' is not defined

您还没有将 return 值分配给任何东西。当您调用 cisco() 时，您需要将 return 值分配给某些东西...请使用：

from ciscoconfparse import CiscoConfParse

def cisco(filename):
    parse = CiscoConfParse(filename)
    TCPSrv = parse.find_objects("service\stcp\sdestination\seq")
    UDPSrv = parse.find_objects("service\sudp\sdestination\seq")
    ObjectNetwork = parse.find_objects("^object\snetwork\s")
    ObjectGroupSrv = parse.find_objects("^object-group\sservice")
    ObjectGroupNetwork = parse.find_objects("^object-group\snetwork\s")
    return TCPSrv, UDPSrv, ObjectNetwork, ObjectGroupSrv, ObjectGroupNetwork

values = cisco("C:\python\mydata\TestConfigFile.txt")
TCPsrv = values[0]
UDPsrv = values[1]
# ... etc unpack the remaining values as illustrated above
