How to create a zip archive of a directory?

The easiest way is to use shutil.make_archive. It supports both zip and tar formats.

import shutilshutil.make_archive(output_filename, 'zip', dir_name)

If you need to do something more complicated than zipping the whole directory (such as skipping certain files), then you'll need to dig into the zipfile module as others have suggested.

As others have pointed out, you should use zipfile. The documentation tells you what functions are available, but doesn't really explain how you can use them to zip an entire directory. I think it's easiest to explain with some example code:

import osimport zipfile    def zipdir(path, ziph):    # ziph is zipfile handle    for root, dirs, files in os.walk(path):        for file in files:            ziph.write(os.path.join(root, file),                        os.path.relpath(os.path.join(root, file),                                        os.path.join(path, '..')))      zipf = zipfile.ZipFile('Python.zip', 'w', zipfile.ZIP_DEFLATED)zipdir('tmp/', zipf)zipf.close()

To add the contents of mydirectory to a new zip file, including all files and subdirectories:

import osimport zipfilezf = zipfile.ZipFile("myzipfile.zip", "w")for dirname, subdirs, files in os.walk("mydirectory"):    zf.write(dirname)    for filename in files:        zf.write(os.path.join(dirname, filename))zf.close()
