如何python中将已有链接的视频进行下载

import requests

def download_videofile(video_links):
    root='保存文件位置'
    for link in video_links:
        file_name = link.split('/')[-1]
        print("Downloading file:%s" % file_name)
        r = requests.get(link, stream=True)
        with open(root+file_name, 'wb') as f:
            for chunk in r.iter_content(chunk_size=1024 * 1024):
                if chunk:
                    f.write(chunk)

        print("%s downloaded!\\n" % file_name)
    print("All videos downloaded!")
    return

if __name__ == "__main__":
    video_links=[视频链接1]
    download_video_series(video_links)

运行结果图如下：
