python 压缩指定文件夹

 # 压缩月文件
    startdir = "{}/searchText/{}".format(settings.base_DIR,strDay[0:10])  # 要压缩的文件夹路径
    file_news = startdir + '.zip' # 压缩文件名称
    z = zipfile.ZipFile(file_news, 'w', zipfile.ZIP_DEFLATED)
    for dirpath, dirnames, filenames in os.walk(startdir):
        fpath = dirpath.replace(startdir, '')
        fpath = fpath and fpath + os.sep or ''
        for filename in filenames:
            z.write(os.path.join(dirpath, filename), fpath + filename)
    z.close()
