python自动zip压缩目录的方法

本文实例讲述了python自动zip压缩目录的方法。分享给大家供大家参考。具体实现方法如下：

这段代码来压缩数据库备份文件，没有使用python内置的zip模块，而是使用了zip.exe文件

# Hello, this script is written in Python - http://www.python.org## autozip.py 1.0p## This script will scan a directory (and its subdirectories)# and automatically zip files (according to their extensions).## This script does not use Python internal ZIP routines.# InfoZip's ZIP.EXE must be present in the path (InfoZip Dos version 2.3).# (zip23x.zip at http://www.info-zip.org/pub/infozip/)## Each file will be zipped under the same name (with the .zip extension)# eg. toto.bak will be zipped to toto.zip## This script is public domain. Feel free to reuse it.# The author is:#    Sebastien SAUVAGE#    <sebsauvage at sebsauvage dot net>#    http://sebsauvage.net## More quick & dirty scripts are available at http://sebsauvage.net/python/## Directory to scan is hardcoded at the end of the script.# Extensions to ZIP are hardcoded below:ext_list = ['.bak','.trn']import os.path, stringdef autozip( directory ):  os.path.walk(directory,walk_callback,'')def walk_callback(args,directory,files):  print 'Scanning',directory  for fileName in files:    if os.path.isfile(os.path.join(directory,fileName)) and string.lower(os.path.splitext(fileName)[1]) in ext_list:      zipMyFile ( os.path.join(directory,fileName) )def zipMyFile ( fileName ):  os.chdir( os.path.dirname(fileName) )  zipFilename = os.path.splitext(os.path.basename(fileName))[0]+".zip"  print ' Zipping to '+ zipFilename  os.system('zip -mj9 "'+zipFilename+'" "'+fileName+'"')autozip( r'C:/mydirectory' )print "All done."
