在列表python中拆分Mac地址

Question

我需要提取存储在python列表中的所有Mac地址中的最后两位数字。

['00:00:00:00:00:02',
 '00:00:00:00:00:01',
 '00:00:00:00:00:03',
 '00:00:00:00:00:01',
 '00:00:00:00:00:04',
 '00:00:00:00:00:01']

我需要从这个列表中提取02，01,010，04，01，还是熊猫数据中的方法？

Answer 1

按最后一个分隔符使用rsplit，并按位置设置最后一个值：

L = ['00:00:00:00:00:02', '00:00:00:00:00:01', '00:00:00:00:00:03',
     '00:00:00:00:00:01', '00:00:00:00:00:04', '00:00:00:00:00:01']

out = [x.rsplit(':', 1)[-1] for x in L]
#alternative
#out = [x.split(':')[-1] for x in L]

或者通过索引获得每个字符串值的最后两个值：

out = [x[-2:] for x in L]

print (out)
['02', '01', '03', '01', '04', '01']

Answer 2

macs = ['00:00:00:00:00:02', '00:00:00:00:00:01', '00:00:00:00:00:03', '00:00:00:00:00:01', '00:00:00:00:00:04', '00:00:00:00:00:01']
short_macs = [x[-2:] for x in macs]

输出

['02', '01', '03', '01', '04', '01']

Answer 3

这将完成你的工作

data=['00:00:00:00:00:02', '00:00:00:00:00:01', '00:00:00:00:00:03', '00:00:00:00:00:01', '00:00:00:00:00:04', '00:00:00:00:00:01']
last_digits=[mac_address.split(':')[-1] for mac_address in data]
print(last_digits)
