Question

我在其中一台服务器上有一个日志文件，我需要编写一个python脚本来复制包含ERROR和INFO标记的行。我希望每次运行脚本时都将带有标签的所有行写入新文件。

这是我到目前为止所写的内容（我是新手）

my_errors=open("/var/tmp/myerrors1.txt", "w")
my_trace=open("/var/tmp/logs/trace1.txt", "r")
my_trace.readline()

x = [INFO, WARN, ERRor]

for line in  my_trace:
    for x in line:
         my_errors.writelines(x)

my_errors.close()
my_trace.close()

trace1.txt示例：

03/17/2015 13:41:55|WARN||ajp-bio-127.0.0.1-4090-exec-5|495233559||_ERR: execute(): Error Response returned 
03/17/2015 13:41:47|INFO||ajp-bio-127.0.0.1-4090-exec-2|495785359||_IN:SearchQuery getList(): ||||

Answer 1

试试这个：

my_errors = open("/var/tmp/myerrors1.txt", "w")
my_trace = open("/var/tmp/logs/trace1.txt", "r")

levels = ['INFO', 'WARN', 'ERROR']

for line in my_trace:
    if any(level in line for level in levels):
        my_errors.write(line)

my_errors.close()
my_trace.close()

使用以下trace1.txt文件进行测试：

03/17/2015 13:41:55|WARN||ajp-bio-127.0.0.1-4090-exec-5|495233559||_ERR: execute(): Error Response returned 
Do not copy this line
03/17/2015 13:41:47|INFO||ajp-bio-127.0.0.1-4090-exec-2|495785359||_IN:SearchQuery getList(): ||||
Do not copy this line

myerrors1.txt档案的结果：

03/17/2015 13:41:55|WARN||ajp-bio-127.0.0.1-4090-exec-5|495233559||_ERR: execute(): Error Response returned 
03/17/2015 13:41:47|INFO||ajp-bio-127.0.0.1-4090-exec-2|495785359||_IN:SearchQuery getList(): ||||

编辑2：

my_errors = open("/var/tmp/myerrors1.txt", "w")
my_trace = open("/var/tmp/logs/trace1.txt", "r")

levels = ['INFO', 'WARN', 'ERROR']

for line in my_trace:
    for level in levels:
        if level in line:
            my_errors.write(line)    

my_errors.close()
my_trace.close()

您还没有指定问题，但我认为您的问题是没有任何内容写入您的文件。您正在将x重新分配给其他内容（line中的值）。您需要为其分配一个不同的变量，如下所示：

my_errors=open("/var/tmp/myerrors1.txt", "w")
my_trace=open("/var/tmp/logs/trace1.txt", "r")
my_trace.readline()

x = [INFO, WARN, ERRor]

for line in  my_trace:
    for message in line: # change from reassigning the x variable to something else
        for error in x: # iterating through the errors in x
            if error in my_trace: # checking if an error is in my_trace
                my_errors.writelines(error) # writing the error

my_errors.close()
my_trace.close()

当然，如果没有完整的信息，这不是最好的答案，但它应该是您可以修复代码的基础。

将错误记录到文件中
