Python's ZipFile implementation file directory decompression

The main problem is to solve the compression and decompression of empty folders in compressed directory.

Functions for compressing folders:

1# coding:utf-82 Import OS3 Import ZipFile4 5 def zipdir (dirtozip,savepath):6     ifNot Os.path.isdir (dirtozip):7Raise Exception,u"zipdir error,not a dir '% '". Format (dirtozip)8 9(savedir,_) =os.path.split (Savepath)Ten     ifNot Os.path.isdir (savedir): One os.makedirs (Savedir) A  -Ziplist = [] -  the      forRoot,dirs,filesinchOs.walk (dirtozip): -          forFileiteminchFiles: - ziplist.append (Os.path.join (root,fileitem)) -          forDiriteminchdirs: + ziplist.append (Os.path.join (root,diritem)) -  +ZF = ZipFile. ZipFile (Savepath,'W', ZipFile. zip_deflated) A  at      forTarinchziplist: -         ifTar! =Dirtozip: -Zf.write (Tar,tar.replace (Dirtozip,"')) -         Else: - zf.write (TAR) -  inZf.close ()

Decompression function:

1 def unzipfile (unzipsrc,targedir):2     ifNot Os.path.isfile (UNZIPSRC):3Raise Exception,u'unzipsrc not exists:{0}'. Format (UNZIPSRC)4 5     ifNot Os.path.isdir (targedir):6 os.makedirs (Targedir)7 8Print (U'Start extracting file: {0}'. Format (UNZIPSRC))9 TenUNZF = ZipFile. ZipFile (UNZIPSRC,'R') One  A      forNameinchunzf.namelist (): -Unzftarge =Os.path.join (targedir,name) -  the         ifUnzftarge.endswith ("/"): - #empty dir -Splitdir = unzftarge[:-1] -             ifNot os.path.exists (splitdir): + os.makedirs (Splitdir) -         Else: +Splitdir,_ =os.path.split (Targedir) A  at             ifNot os.path.exists (splitdir): - os.makedirs (Splitdir) -  -hfile = open (Unzftarge,'WB') - Hfile.write (Unzf.read (name)) - hfile.close () in  -Print (U'decompression complete, target file directory: {0}'. Format (targedir)) to  +Unzf.close ()

Call:

if ' __main__ ' :     = Os.path.abspath (U'. \\new')    = Os.path.abspath (u'. \ \) New.zip') #    Zipdir (Dirpath,savepath)    unzipfile (Savepath,dirpath)
