我正在尝试清理日志，我想删除一些特殊字符串
例子:
%/h > %/h Current value over threshold value
Pg/S > Pg/S Current value over threshold value
Pg/S > Pg/S No. of pages paged in exceeds threshold
MB < MB min. avg. value over threshold value
我尝试过使用一些模式，但似乎不起作用。
re.sub(r'\w\w\/\s>\s\w','',text)
我有什么好主意可以去除特殊图案吗？
我想删除 .../...>.../...
我希望我的输出只包含有用的词。
Current value over threshold value
No. of pages paged in exceeds threshold
min. avg. value over threshold value
谢谢你的想法!
请您参考如下方法:
假设文件的结构是:
[special-string] [< or >] [special-string] [message]
那么这应该可以工作:
>>> rgx = re.compile(r'^[^<>]+[<>] +\S+ +', re.M)
>>>
>>> s = """
... %/h > %/h Current value over threshold value
... Pg/S > Pg/S Current value over threshold value
... Pg/S > Pg/S No. of pages paged in exceeds threshold
... MB < MB min. avg. value over threshold value
... """
>>>
>>> print(rgx.sub('', s))
Current value over threshold value
Current value over threshold value
No. of pages paged in exceeds threshold
min. avg. value over threshold value
