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‘, ‘macAddr‘: ‘2c:44:fd:7f:56:a4‘},
 {‘name‘: ‘eth5‘, ‘macAddr‘: ‘d8:9d:67:f2:ef:74‘},
 {‘name‘: ‘eth3‘, ‘macAddr‘: ‘2c:44:fd:7f:56:a7‘},
 {‘name‘: ‘eth1‘, ‘macAddr‘: ‘2c:44:fd:7f:56:a5‘}, 
{‘name‘: ‘eth4‘, ‘macAddr‘: ‘d8:9d:67:f2:ef:70‘}, 
{‘name‘: ‘eth2‘, ‘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".......]

代码：
lis = [ i[‘macAddr‘]  for i in 列表 ]
