怎么用python做一个解压缩小工具，以后再也不用下载各种格式的解压缩软件了...

import os

    zip文件压缩

            path_file = os.path.join(parent, filename)
            arcname = path_file[pre_len:].strip(os.path.sep)
            zip_file.write(path_file, arcname)

    zip_file.close()

        zip_file.extract(names, target_)
    zip_file.close()
