Question

我有一个包含字符串output的文件，如下面的代码所示。我想提取数据：

如何使用正则表达式实现此目的？我可以将我使用的两个正则表达式合并为一个吗？

我还需要忽略"dropped"字符串

port: dropped-packets
s1-eth1: 21
s1-eth2: 12
...

'''

我的代码：

import re
searchObj = re.findall( r's\d-eth\d', output, re.M|re.I)
searchObj2 = re.findall( r'dropped \d*', output, re.M|re.I)

print searchObj
print searchObj2

我得到的输出：

['s2-eth2', 's2-eth3', 's2-eth4', 's2-eth5', 's2-eth6', 's3-eth2', 's3-eth3', 's3-eth4', 's3-eth5', 's3-eth6', 's4-eth2', 's4-eth3', 's4-eth4', 's4-eth5', 's4-eth6', 's4-eth7', 's4-eth8', 's4-eth9', 's4-eth1', 's4-eth1', 's6-eth2', 's6-eth3', 's6-eth4', 's6-eth5', 's6-eth6', 's2-eth1', 's2-eth1', 's1-eth1', 's1-eth1', 's3-eth1', 's1-eth2', 's4-eth1', 's1-eth3', 's5-eth1', 's1-eth4', 's6-eth1', 's1-eth5']
['dropped 0', 'dropped 0', 'dropped 0', 'dropped 0', 'dropped 0', 'dropped 0', 'dropped 0', 'dropped 0', 'dropped 0', 'dropped 0', 'dropped 0', 'dropped 0', 'dropped 0', 'dropped 0', 'dropped 0', 'dropped 0', 'dropped 0', 'dropped 0', 'dropped 0', 'dropped 0', 'dropped 0', 'dropped 0', 'dropped 0', 'dropped 0', 'dropped 0', 'dropped 0', 'dropped 0', 'dropped 3', 'dropped 3', 'dropped 21', 'dropped 21', 'dropped 0', 'dropped 0', 'dropped 0', 'dropped 0', 'dropped 0', 'dropped 0', 'dropped 0', 'dropped 0']

Answer 1

您可以在正则表达式之间使用逻辑OR：

>>> re.findall( r's\d-eth\d|dropped \d*', output, re.M|re.I)
['dropped 0', 'dropped 0', 's2-eth2', 'dropped 0', 's2-eth3', 'dropped 0', 's2-eth4', 'dropped 0', 's2-eth5', 'dropped 0', 's2-eth6', 'dropped 0', 's3-eth2', 'dropped 0', 's3-eth3', 'dropped 0', 's3-eth4', 'dropped 0', 's3-eth5', 'dropped 0', 's3-eth6', 'dropped 0', 's4-eth2', 'dropped 0', 's4-eth3', 'dropped 0', 's4-eth4', 'dropped 0', 's4-eth5', 'dropped 0', 's4-eth6', 'dropped 0', 's4-eth7', 'dropped 0', 's4-eth8', 'dropped 0', 's4-eth9', 'dropped 0', 's4-eth1', 'dropped 0', 's4-eth1', 'dropped 0', 's6-eth2', 'dropped 0', 's6-eth3', 'dropped 0', 's6-eth4', 'dropped 0', 's6-eth5', 'dropped 0', 's6-eth6', 'dropped 0', 's2-eth1', 'dropped 3', 's2-eth1', 'dropped 3', 's1-eth1', 'dropped 21', 's1-eth1', 'dropped 21', 's3-eth1', 'dropped 0', 's1-eth2', 'dropped 0', 's4-eth1', 'dropped 0', 's1-eth3', 'dropped 0', 's5-eth1', 'dropped 0', 's1-eth4', 'dropped 0', 's6-eth1', 'dropped 0', 's1-eth5', 'dropped 0']

如果您不想在结果中使用dropped字词，那么您可以在正则表达式中使用正面外观：

>>> re.findall( r's\d-eth\d|(?<=dropped) ?\d*|eth\d', output, re.M|re.I)
['eth0', ' 0', 'eth1', ' 0', 's2-eth2', ' 0', 's2-eth3', ' 0', 's2-eth4', ' 0', 's2-eth5', ' 0', 's2-eth6', ' 0', 's3-eth2', ' 0', 's3-eth3', ' 0', 's3-eth4', ' 0', 's3-eth5', ' 0', 's3-eth6', ' 0', 's4-eth2', ' 0', 's4-eth3', ' 0', 's4-eth4', ' 0', 's4-eth5', ' 0', 's4-eth6', ' 0', 's4-eth7', ' 0', 's4-eth8', ' 0', 's4-eth9', ' 0', 's4-eth1', ' 0', 's4-eth1', ' 0', 's6-eth2', ' 0', 's6-eth3', ' 0', 's6-eth4', ' 0', 's6-eth5', ' 0', 's6-eth6', ' 0', 's2-eth1', ' 3', 's2-eth1', ' 3', 's1-eth1', ' 21', 's1-eth1', ' 21', 's3-eth1', ' 0', 's1-eth2', ' 0', 's4-eth1', ' 0', 's1-eth3', ' 0', 's5-eth1', ' 0', 's1-eth4', ' 0', 's6-eth1', ' 0', 's1-eth5', ' 0']
