在关键字python之后打印字符串
我设法从txt文件中提取以下行在关键字python之后打印字符串,python,regex,string,file,Python,Regex,String,File,我设法从txt文件中提取以下行 05/19/2014, 15:24:14.455> LVL:2 RC: 0 SERVER :server main: TERA_MGMT_SYS_SESS_EVENT_RESET with disconnect cause (0x105) 现在如何从中拉出105 #!/usr/bin/env python import sys, re, os lineContains = re.compile(r'(?=.*disconnect c

print 'code not found in KB.'
filename.close()
给出错误文件“pcoip\u disconnect\u codes.py”,第20行
elif代码==102:
^
缩进错误:未缩进与任何外部缩进级别不匹配您可以尝试下面的正则表达式来获取
()
中的数字。下面的正则表达式包含字符串cause
,因为它有助于正确匹配确切的行以及()
中的数字
你的代码是
lineContainsCode = re.compile(r'cause \(.*?(\d+)\)')
对于非正则表达式方法:
code = line.split("(")[-1].split(")")[0].split("x")[-1]
# more readable:
# code = line.split("(")[-1]
# .split(")")[0]
# .split("x")[-1]
这将拆分所有文本打开参数上的字符串,并在-1
上建立索引(即抓取最后一个)。然后在所有文本闭合区拆分,并在0
上建立索引(即抓取第一个),然后在所有文本“x”
s上拆分,并在-1
上建立索引(即抓取最后一个)
导致105
编辑HASHMAP示例:
code = lineContainsCode.search(line).group(1)
hashmap = {"001":'PCoIP session terminated due to lost network.',
"100":'PCoIP connection not established due to failure of PCoIP server initialization. This should not occur. Please contact Teradici support.',
...
"407":'PCoIP connection not established due to the View Security Server detecting that AES encryption is disabled on either the client and/or server.'}
error_msg = hashmap.get(code,'code not found in KB.')
print(error_msg)
我用了这个,它打印出0x105,有没有办法只拉出105。我真的很不擅长,请@Adam Smith'code=lineContainsCode.search(line.group)(1)如果code='150',请打印代码:{print('see kb')}'尝试使用if,但似乎不起作用,并给我错误提示:文件“pcoip_disconnect_code.py”,第17行打印('see kb')^Syntaxer:无效syntax@user3731311你写python有多久了?不要用大括号来表示代码块……不太长,我也尝试过删除{}。在获得代码后,我尝试了“if code==150:print”使用此“”似乎不起作用work@Adam史密斯:谢谢你所做的一切help@user3731311如果没有看到完整的代码,很难说:)'code=lineContainsCode.search(line.group)(1)如果code='150',则打印代码:{print('see kb')}'尝试使用if但似乎不起作用,并给出错误提示:文件“pcoip_disconnect_codes.py”,第17行打印('see kb')^SyntaxError:invalid syntax@Rakesh KR
