zipfile module:

• Zipping above mentioned files

  import zipfile
  zipfile_object = zipfile.ZipFile('compression_file.zip', 'w')
  zipfile_object.write('file_one.txt', compress_type= zipfile.ZIP_DEFLATED)
  zipfile_object.write('file_two.txt', compress_type= zipfile.ZIP_DEFLATED)
  zipfile_object.close()
  

• Unzipping above mentioned archive file

  import zipfile
  zipfile_object = zipfile.ZipFile('compression_file.zip', 'r')
  zipfile_object.extractall('extracted_contented')
  

shutil module:

• shutil module also used to make and unpack archive. This uses folder as source while making archive while uses file while upacking archive as source

• making archive from directory as source. second parameter in make_archive represent format of archive. It may - ‘zip’ or ‘tar’

   import os
   import shutil
   current_dir = os.getcwd()
   dir_to_zip = current_dir + '//extracted_contented'
   zip_file_name = 'directory_zip'
   shutil.make_archive(zip_file_name, 'zip', dir_to_zip);
  

  • upacking archive from file to destination directory. third parameter is format of archive. It may - ‘zip’ or ‘tar’

    import os
    import shutil
    current_dir = os.getcwd()
    zip_file_name = 'directory_zip.zip'
    zip_to_dir = current_dir + '//unpack_content'
    shutil.unpack_archive(zip_file_name, zip_to_dir, 'zip' )
