import urllib.request
import gevent
from gevent import monkey

monkey.patch_all()


def downloader(img_name, img_url):
    req = urllib.request.urlopen(img_url)

    img_content = req.read()

    with open(img_name, "wb") as f:
        f.write(img_content)


def main():
    gevent.joinall([
        gevent.spawn(downloader, "3.jpg",
                     "https://rpic.douyucdn.cn/live-cover/appCovers/2019/04/01/6411910_20190401003227_small.jpg?x-oss-process=image/format,webp"),
        gevent.spawn(downloader, "4.jpg",
                     "https://rpic.douyucdn.cn/live-cover/appCovers/2019/04/12/278227_20190412181615_small.jpg?x-oss-process=image/format,webp")
    ])


if __name__ == '__main__':
    main()
