How do I zip the contents of a folder using python

问题:

Once I have all the files I require in a particular folder, I would like my python script to zip the folder contents.

Is this possible?

And how could I go about doing it?

回答1:

Adapted version of the script is:

#!/usr/bin/env python
from __future__ import with_statement
from contextlib import closing
from zipfile import ZipFile, ZIP_DEFLATED
import os

def zipdir(basedir, archivename):
    assert os.path.isdir(basedir)
    with closing(ZipFile(archivename, "w", ZIP_DEFLATED)) as z:
        for root, dirs, files in os.walk(basedir):
            #NOTE: ignore empty directories
            for fn in files:
                absfn = os.path.join(root, fn)
                zfn = absfn[len(basedir)+len(os.sep):] #XXX: relative path
                z.write(absfn, zfn)

if __name__ == '__main__':
    import sys
    basedir = sys.argv[1]
    archivename = sys.argv[2]
    zipdir(basedir, archivename)

Example:

C:\zipdir> python -mzipdir c:\tmp\test test.zip

It creates 'C:\zipdir\test.zip' archive with the contents of the 'c:\tmp\test' directory.

On python 2.7 you might use: shutil.make_archive(base_name, format[, root_dir[, base_dir[, verbose[, dry_run[, owner[, group[, logger]]]]]]]).

base_name archive name minus extension

format format of the archive

root_dir directory to compress.

For example

 shutil.make_archive(target_file, format="bztar", root_dir=compress_me)

Here is a recursive version

def zipfolder(path, relname, archive):
    paths = os.listdir(path)
    for p in paths:
        p1 = os.path.join(path, p) 
        p2 = os.path.join(relname, p)
        if os.path.isdir(p1): 
            zipfolder(p1, p2, archive)
        else:
            archive.write(p1, p2) 

def create_zip(path, relname, archname):
    archive = zipfile.ZipFile(archname, "w", zipfile.ZIP_DEFLATED)
    if os.path.isdir(path):
        zipfolder(path, relname, archive)
    else:
        archive.write(path, relname)
    archive.close()
