爬虫爬取时名称无法变换

Question

前面是拼接以及爬取的过程，因为较长就省略了，前面有for循环，所以字典有缩进，从字典取值开始，前面还有个urls列表，
现在的问题：爬取时，因为视频名称不能变换，所以总是把爬取到的视频覆盖掉，导致最后只有一个视频
问：如何把名字也带上

    dic={
        'name':video_name,
        'url':video_true_url
    }
    urls.append(dic['url'])
    name_list=dic['name']

async def get_video_data(url):
    print('开始下载',name_list,'...')
    async with aiohttp.ClientSession() as session:
        async with await session.get(url,headers=headers) as response:
            data=await response.read()
            with open(name_list,'wb') as fp:
                fp.write(data)
                print(name_list,'下载成功！')

stasks=[]
for url in urls:
    c=get_video_data(url)
    task=asyncio.ensure_future(c)
    stasks.append(task)

loop=asyncio.get_event_loop()
loop.run_until_complete(asyncio.wait(stasks))

Answer 1

import os
import datetime
name_list=os.path.splitext(dic['name'])
name_list="".join([name_list[0],'_',datetime.datetime.now().strftime('%Y%m%d%H%M%S%f'),name_list[-1]])
