Question

我是Python的新手，我已经写了一些代码，当我运行代码时，出现了一些编译错误。有人可以帮我找出问题所在。

这是我的temp.log文件中包含的内容：

06 May 19 03:40:35 3 abCodeClearTrap Error Clear Trap (agent: 12367a12, 
chassis:12367a12, ErrIdText: ERROR ID TEXT, csssi: EXTIFG, clearedID: 
0x089088394)
06 May 19 03:44:35 3 abCodeErrorTrap Error Trap (agent: 12368a15, chassis: 
12368a15, ErrIdText: Skip this item, csssi: SSRSSR, clearedID: 
0x089088394)

到目前为止，我有一些代码：＃！/ usr / bin / python 汇入

 with open('temp.log') as f:
     lines = f.readlines()

 data = []
 for line in lines:

     date = re.match(r'\d{2} \w+ \d{2}', lines).group(0)
     time = lines.split()[3]
     ids = lines.split()[4]
     agent = re.search(r'agent:\s(.*?),', lines).group(1)        
     errID = re.search(r'ErrIdText:\s(.*?),', lines).group(1)
     clear = re.search(r'clearedID:\s(.*?)\)', lines).group(1)

     row = [date, time, ids, agent, errID, clear]
     data.append(row)

 for row in data:
     print(row)

运行上面的代码时，我得到了：

 Traceback (most recent call last):
 File "./practice.py", line 10, in <module>
   date = re.match(r'\d{2} \w+ \d{2}', lines).group(0)
 File "/usr/lib64/pythong2.7/re.py", line 137, in match
   return _compile(patter, flags).match(string)
 TypeError: expected string or buffer

此外，如果我注释掉第10行，则遇到的下一个错误是：

 Traceback (most recent call last):
 File "./practice.py", line 11, in <module>
 time = lines.split()[3]
 AttributeError: 'list' object has no attribute 'split'

任何人都可以帮助我找出这些错误。

非常感谢

Answer 1

正如错误所言，lines是一个列表。大概您打算在整个for循环中使用line。

date = re.match(r'\d{2} \w+ \d{2}', line).group(0)
time = line.split()[3]
...

这是您代码的有效版本。一些拼写错误，例如line而不是lines和group（）而不是group（0），但您做得很好。

import re

with open('temp.log') as f:
    lines = f.readlines()

data = []
for line in lines:
    date = re.match(r'\d{2} \w+ \d{2}', line).group()    
    time = line.split()[3]
    ids = line.split()[4]

    try:
        agent = re.search(r'agent:\s(.*?),', line).group()
    except:
        agent = 'agent:'
    try:
        errID = re.search(r'ErrIdText:\s(.*?),', line).group()
    except:
        errID = 'ErrIdText:'
    try:
        clear = re.search(r'clearedID:\s(.*?)\)', line).group()
    except:
        clear = 'clearedID:'

    row = [date, time, ids, agent, errID, clear]
    data.append(row)

for row in data:
     print(row)

编辑：添加尝试，除非在日志文件中找不到关键字

结果：

['06 May 19', '03:40:35', '3', 'agent: 12367a12,', 'ErrIdText: ERROR ID TEXT,', 'clearedID: 0x089088394)']
['06 May 19', '03:44:35', '3', 'agent: 12368a15,', 'ErrIdText: Skip this item,', 'clearedID: 0x089088394)']
