创建日志文件

Question

我是这里的新手，还是编程的新手。

我的问题是，我的程序应该在运行期间创建一个日志文件 。

它看起来应该像这样：

开始复制“ Log X” | 至今 时间

开始压缩“ Log X” | 至今 时间| 文件服务

Ende压缩“ Log X” | 至今 时间| 文件服务

开始删除“ Log X” | 至今 时间

结束删除“ Log X” | 至今 时间

...

'“ Log X”表示文件名

当我再次运行程序时，“新日志文件”应附加到“旧文件”

到目前为止，这是我的程序代码：

import os, datetime, zipfile

def showProgramInformation():
    print " "
    print "#######################################################"
    print "Python Log-Packer.py  Ver. 1.4"
    print "Search for files, separate the .log fils, compress them" 
    print "and delete the origin file"
    print "log-File = Files with '.log' in name" 
    print "#######################################################"
    print " "

日志记录模块定义了实现用于应用程序和库的灵活事件日志记录系统的函数和类。

FORMAT = '%(asctime)-15s %(clientip)s %(user)-8s %(message)s'
logging.basicConfig(format=FORMAT)
d = {'clientip': '192.168.0.1', 'user': 'fbloggs'}
logger = logging.getLogger('tcpserver')
logger.warning('Protocol problem: %s', 'connection reset', extra=d)

将打印类似

2006-02-08 22:20:02,165 192.168.0.1 fbloggs  Protocol problem: connection reset

您可以使用Formatter定义自己的输出格式，并使用不同的LogRecord属性将记录中的数据合并到格式字符串中。
