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, string
    def 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."
