package into zip file

Import ZipFile
f = zipfile. ZipFile (' Archive.zip ', ' W ', ZipFile. zip_deflated)
f.write (' file_to_add.py ')
f.close ()

unpack from zip file

Import os,sys  
import zipfile  
import re
os.chdir ('/home/wangyue/brain/geneexpression ') all

= Os.listdir ('. ')

For II in all:
    B = re.match (' \d+ ', ii)
    if B:        
        zfile = II
        z = zipfile. ZipFile (Zfile, mode= ' R ')
        os.mkdir (' un ' + II) for
        JJ in z.filelist:
            data = Z.read (JJ)            
            fd = open ('./' + ' UN ' +ii+ '/' +jj.filename, ' WB ')     
            fd.write (data)
            Fd.close ()

package The files in the entire folder

Import ZipFile
f = zipfile. ZipFile (' Archive.zip ', ' W ', ZipFile. zip_deflated)
Startdir = "C:\\mydirectory"
for Dirpath, Dirnames, filenames in Os.walk (startdir):
    for FileName in filenames:
        f.write (Os.path.join (dirpath,filename))
F.close ()

Compress and decompress tar.gz files

First decompression

Import tarfile
import OS
def untar (fname, dirs):
    t = Tarfile.open (fname)
    t.extractall (path = dirs) 

if __name__ = = "__main__":
    Untar ("del.tar.gz", ".")

Again is compression

Import tarfile
import OS
def tar (fname):
    t = tarfile.open (fname + ". tar.gz", "W:gz") for
    root, dir, files In Os.walk (fname):
        print root, dir, files to
        file in files:
            FullPath = os.path.join (root, file)
            T.add (f Ullpath)
    t.close ()

if __name__ = = "__main__":
    tar ("del")
