[英]mapping a list to a dict when the keys are weird
I want to process LLDP data from a TP-Link switch in an inventory plugin for Check_MK. 我想处理来自Check_MK清单插件中TP-Link交换机的LLDP数据。 The TP-Link switch doesn't use the standard SNMP OIDs for LLDP and their custom MIB has a weird quirk.
TP-Link交换机不对LLDP使用标准的SNMP OID,并且它们的自定义MIB有一个怪异的现象 。 Instead of having an index at the end of the OIDs they put it in the middle of the OID.
而不是在OID的末尾添加索引,而是将其放在OID的中间。
[[[u'1.1.99353.1', u'Te1/0/25'], [u'1.2.99353.1', u'1'], [u'1.3.99353.1', u'MAC address'], [u'1.4.99353.1', u'00:zzzzzzz'], [u'1.5.99353.1', u'MAC address'], [u'1.6.99353.1', u'00:zzzzzzzz'], [u'1.7.99353.1', u'120'], [u'1.8.99353.1', u'Port 25'], [u'1.9.99353.1', u'THE_HOST_NAME'], [u'1.11.99353.1', u'Bridge Router'], [u'1.12.99353.1', u'Bridge Router'], [u'shortened', u'for brevity']]
[[[u'1.1.99353.1',u'Te1 / 0/25'],[u'1.2.99353.1',u'1'],[u'1.3.99353.1',u'MAC地址'],[ u'1.4.99353.1',u'00:zzzzzzz'],[u'1.5.99353.1',u'MAC地址'],[u'1.6.99353.1',u'00:zzzzzzzz'',[u'1.7 .99353.1',u'120'],[u'1.8.99353.1',u'Port 25'],[u'1.9.99353.1',u'THE_HOST_NAME'],[u'1.11.99353.1',u'Bridge路由器'],[u'1.12.99353.1',u'桥路由器'],[u'shortened',u'for br'ity']
So on planet normal, I would expect things like 99353. 8 and 99353. 9 or maybe 99353.1. 因此,在正常的星球上,我期望像99353. 8和99353. 9或99353.1。之类的东西。 8 and 99353.1.
8和99353.1。 9 .
9 。 What they do here (1. X .99353.1) is odd.
他们在这里所做的工作(1. X .99353.1)很奇怪。 I am not sure what to do with it.
我不确定该怎么办。 All I know is I have to normalize it and I'm too stupid to do that.
我所知道的是我必须将其标准化,而我太愚蠢了。
This is what I would like to make from it: 这是我想从中得到的:
{
l_id : 99353.1 # from the "index"
l_ifname : u'Te1/0/25' # from 1.1
r_ifname : u'Port 25' # from 1.8
r_hostname : u'THE_HOST_NAME' # from 1.9.
}
Mapping this (only a subset of the list, while splitting up the key-to-be is completely above my skill level. I would like to avoid spending half a day to produce something ugly with a pile of for-loops. especially since this should go upstream to a community project and I don't want anyone to hurt their eyes. 映射它(只是列表的一个子集,同时拆分要创建的键完全超出了我的技能水平。我想避免花半天时间用一堆for循环生成难看的东西。尤其是因为这应该去社区项目上游,我不希望任何人伤到他们的眼睛。
Is there some smart approach that lets me break this into 2-3 smaller problems? 有什么聪明的方法可以让我将其分解为2-3个较小的问题吗?
You can use string.split to make a dict of the indexes: 您可以使用string.split来编写索引的字典:
list_ = [[u'1.1.99353.1', u'Te1/0/25'], [u'1.2.99353.1', u'1'], [u'1.3.99353.1', u'MAC address'], [u'1.4.99353.1', u'00:zzzzzzz'], [u'1.5.99353.1', u'MAC address'], [u'1.6.99353.1', u'00:zzzzzzzz'], [u'1.7.99353.1', u'120'], [u'1.8.99353.1', u'Port 25'], [u'1.9.99353.1', u'THE_HOST_NAME'], [u'1.11.99353.1', u'Bridge Router'], [u'1.12.99353.1', u'Bridge Router'], [u'shortened', u'for brevity']]
dict_ = {key.split(".")[1]: val for key, val in list_[:-1]}
which gives you 这给你
{'1': 'Te1/0/25',
'11': 'Bridge Router',
'12': 'Bridge Router',
'2': '1',
'3': 'MAC address',
'4': '00:zzzzzzz',
'5': 'MAC address',
'6': '00:zzzzzzzz',
'7': '120',
'8': 'Port 25',
'9': 'THE_HOST_NAME'}
From there it's easy to make the dictionary you're after 从那里很容易制作您想要的字典
output = {
"l_id": list_[0][0].split(".", 2)[-1],
"l_ifname": dict_["1"],
"l_rname": dict_["8"],
"r_hostname": dict_["9"],
}
