python列表里面有多个字典，怎么取出每个字典特定key的value组成列表？
列表如下
[
{'name': 'eth0', 'description': 'Broadcom Inc. and subsidiaries NetXtreme BCM5719 Gigabit Ethernet PCIe', 'status': '1', 'macAddr': '2c:44:fd:7f:56:a4'},
{'name': 'eth5', 'description': 'Emulex Corporation OneConnect 10Gb NIC (be3)', 'status': '0', 'macAddr': 'd8:9d:67:f2:ef:74'},
{'name': 'eth3', 'description': 'Broadcom Inc. and subsidiaries NetXtreme BCM5719 Gigabit Ethernet PCIe', 'status': '1', 'macAddr': '2c:44:fd:7f:56:a7'},
{'name': 'eth1', 'description': 'Broadcom Inc. and subsidiaries NetXtreme BCM5719 Gigabit Ethernet PCIe', 'status': '1', 'macAddr': '2c:44:fd:7f:56:a5'},
{'name': 'eth4', 'description': 'Emulex Corporation OneConnect 10Gb NIC (be3)', 'status': '0', 'macAddr': 'd8:9d:67:f2:ef:70'},
{'name': 'eth2', 'description': 'Broadcom Inc. and subsidiaries NetXtreme BCM5719 Gigabit Ethernet PCIe', 'status': '0', 'macAddr': '2c:44:fd:7f:56:a6'}
]
取出每个列表key为macAddr的对应value，组成列表，例如这种
["2c:44:fd:7f:56:a4","d8:9d:67:f2:ef:74".......]

all_adapter=[{'name': 'eth0', 'description': 'Broadcom Inc. and subsidiaries NetXtreme BCM5719 Gigabit Ethernet PCIe', 'status': '1', 'macAddr': '2c:44:fd:7f:56:a4'}, \
{'name': 'eth5', 'description': 'Emulex Corporation OneConnect 10Gb NIC (be3)', 'status': '0', 'macAddr': 'd8:9d:67:f2:ef:74'},  \
{'name': 'eth3', 'description': 'Broadcom Inc. and subsidiaries NetXtreme BCM5719 Gigabit Ethernet PCIe', 'status': '1', 'macAddr': '2c:44:fd:7f:56:a7'}, \
{'name': 'eth1', 'description': 'Broadcom Inc. and subsidiaries NetXtreme BCM5719 Gigabit Ethernet PCIe', 'status': '1', 'macAddr': '2c:44:fd:7f:56:a5'}, \
{'name': 'eth4', 'description': 'Emulex Corporation OneConnect 10Gb NIC (be3)', 'status': '0', 'macAddr': 'd8:9d:67:f2:ef:70'}, \
{'name': 'eth2', 'description': 'Broadcom Inc. and subsidiaries NetXtreme BCM5719 Gigabit Ethernet PCIe', 'status': '0', 'macAddr': '2c:44:fd:7f:56:a6'}]

macAddrList=[]
for net_adapter_dict in all_adapter:
    macAddrList.append(net_adapter_dict['macAddr'])
    
print(macAddrList)

[v for k,v in ***.items] #***为字典名字

[weixin_43712138]

[v for k,v in ***.items if k ==macAddr] #***为字典名称

@chuifengde 谢谢

[Tyaing]

@chuifengde 学到了，这个方法最简便

[chuifengde]

l = [ i['macAddr']  for i in 列表 ]

[weixin_43712138]

b = [{'name': 'eth0', 'description': 'Broadcom Inc. and subsidiaries NetXtreme BCM5719 Gigabit Ethernet PCIe', 'status': '1', 'macAddr': '2c:44:fd:7f:56:a4'}, {'name': 'eth5', 'description': 'Emulex Corporation OneConnect 10Gb NIC (be3)', 'status': '0', 'macAddr': 'd8:9d:67:f2:ef:74'}, {'name': 'eth3', 'description': 'Broadcom Inc. and subsidiaries NetXtreme BCM5719 Gigabit Ethernet PCIe', 'status': '1', 'macAddr': '2c:44:fd:7f:56:a7'}, {'name': 'eth1', 'description': 'Broadcom Inc. and subsidiaries NetXtreme BCM5719 Gigabit Ethernet PCIe', 'status': '1', 'macAddr': '2c:44:fd:7f:56:a5'}, {'name': 'eth4', 'description': 'Emulex Corporation OneConnect 10Gb NIC (be3)', 'status': '0', 'macAddr': 'd8:9d:67:f2:ef:70'}, {'name': 'eth2', 'description': 'Broadcom Inc. and subsidiaries NetXtreme BCM5719 Gigabit Ethernet PCIe', 'status': '0', 'macAddr': '2c:44:fd:7f:56:a6'}] c = [] for i in b: a = [v for k,v in i.items() if 'macAddr' == k] c.append(a) print(c)

[giter888]

list_result = [item['macAddr'] for item in data]

[还有名字可以起吗]

同问，不知如何解决的

##这里我只取了name和status两个字段作为例子。 data = [ {'name': 'eth0', 'description': 'Broadcom Inc. and subsidiaries NetXtreme BCM5719 Gigabit Ethernet PCIe', 'status': '1', 'macAddr': '2c:44:fd:7f:56:a4'}, {'name': 'eth5', 'description': 'Emulex Corporation OneConnect 10Gb NIC (be3)', 'status': '0', 'macAddr': 'd8:9d:67:f2:ef:74'}, {'name': 'eth3', 'description': 'Broadcom Inc. and subsidiaries NetXtreme BCM5719 Gigabit Ethernet PCIe', 'status': '1', 'macAddr': '2c:44:fd:7f:56:a7'}, {'name': 'eth1', 'description': 'Broadcom Inc. and subsidiaries NetXtreme BCM5719 Gigabit Ethernet PCIe', 'status': '1', 'macAddr': '2c:44:fd:7f:56:a5'}, {'name': 'eth4', 'description': 'Emulex Corporation OneConnect 10Gb NIC (be3)', 'status': '0', 'macAddr': 'd8:9d:67:f2:ef:70'}, {'name': 'eth2', 'description': 'Broadcom Inc. and subsidiaries NetXtreme BCM5719 Gigabit Ethernet PCIe', 'status': '0', 'macAddr': '2c:44:fd:7f:56:a6'} ] end_list = [] for item in data: dic_key = {} dic_key['name'] = item['name'] dic_key['status'] = item['status'] end_list.append(dic_key) print(end_list) ####### [{'name': 'eth0', 'status': '1'}, {'name': 'eth5', 'status': '0'}, {'name': 'eth3', 'status': '1'}, {'name': 'eth1', 'status': '1'}, {'name': 'eth4', 'status': '0'}, {'name': 'eth2', 'status': '0'}]

参考下jsonpath

[weixin_40966318]

from operator import itemgetter map(itemgetter('macAddr'), list_variable)
