If you are facing problem of ''RuntimeError: Event loop is closed'' in Windows then
Just replace this code ''asyncio.run(main())''
with

asyncio.run(main())
Especially in the async_scraper.py file, Thanks.

You mentioned, we can't use beautifulsoup with async, then what's the alternative?

[pythonically]

please make a video on how we can convert our scrapy project into an exe file? I tried to search on youtube but failed to find even a single video. I also go through some answers in StackOverflow but am unable to understand what is happening ...

Sir I am facing a problem., sir can u tell me how to download a image in a website in a canvas tag with no url

[wdmtaj]

I'm having trouble with your code. When I run just one url, it is fast. Two or more urls take 20 seconds or more. Can you help?

import re
import aiohttp
import asyncio
import time

start_time = time.time()

]
]

async def get_response(session, url):
async with session.get(url) as resp:
text = await resp.text()
exp = r'(<title>).*(<\/title>)'
return re.search(exp, text).group(0)


async def main():
async with aiohttp.ClientSession() as session:

tasks = []
for url in links:
tasks.append(asyncio.create_task(get_response(session, url)))

results = await asyncio.gather(*tasks)
for result in results:
print(result)



asyncio.run(main())
print("--- %s seconds ---" % (time.time() - start_time))
