從json輸出中提取多個字段

Question

嗨，夥計們，我想問問題，但我想知道是什麼過程，以從下面的json輸出中刪除'name'值，我知道如何獲取單個名稱索引name = [groups['groups'][0]['name'] for groups in result]但我如何得到這兩個名字

from pyzabbix import ZabbixAPI 

import json 

z = ZabbixAPI(url='https://zabbix.server,user='xxxx',password='xxxx') 
result = z.host.get(output='groupid',selectGroups='extend', filter={'host' : 'mailpphfprd01'}) 


name = [groups['groups'] for groups in result] 

name 

JSON輸出：

[[{u'flags': u'0', 
    u'groupid': u'110', 
    u'internal': u'0', 
    u'name': u'- GSOC - Systems'}, 
    {u'flags': u'0', 
    u'groupid': u'313', 
    u'internal': u'0', 
    u'name': u'Applications - Email Digest'}]] 

需要的輸出

[u'- GSOC - Systems' u'Applications - Email Digest']

你應該能夠做到這一點的一個list-comprehension：

json_output = [ 
    [ 
    { 
     "internal": "0", 
     "flags": "0", 
     "groupid": "110", 
     "name": "- GSOC - Systems" 
    }, 
    { 
     "internal": "0", 
     "flags": "0", 
     "groupid": "313", 
     "name": "Applications - Email Digest" 
    } 
    ] 
] 

names = [d['name'] for d in json_output[0]] 

print(names) # -> [u'- GSOC - Systems', u'Applications - Email Digest']
