python里面如何压缩文件目录后，将压缩包放到另一个目录，请给出相应的代码

import os
os.rename('packages.zip', 'directoryYouWantToMoveTo'+r'\packages.zip')

应该也可以

def zip_folder( foldername, filename):

        # empty dir 
        if  len(files) == 0:
            print 'empty dir'
            zif=zipfile.ZipInfo((root+'/').encode("gbk"+"/"))
            zip.writestr(zif,"")
    zip.close()
    print "Finish compressing"


if __name__ == "__main__":
    folder = 'test'
    filename = 'test.zip'
    zip_folder( folder, filename )
