创建日志文件

Question

i'm new here and a beginner in programming.

My problem is, my program should create a log-files during it runs.

It should look like this:

Start Copy "Log X" | Date-today | Time

Start Compress "Log X" | Date-today | Time | File sice

Ende Compress "Log X" | Date-today | Time | File sice

Start Delete "Log X" | Date-today | Time

End Delete "Log X" | Date-today | Time

...

' "Log X" means the name of the File

When i run the program again the "new log-file" should attachment to the "old file"

This is my program-code till now:

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 " "

It would be nice if they could help me. (Sorry if my english is no so good)

The logging module defines functions and classes which implement a flexible event logging system for applications and libraries.

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)

would print something like

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

You can use a Formatter to define your own output format and use the different LogRecord attributes to merge data from the record into the format string.
