Im trying to run this function every 2seconds forever :

import requests
from bs4 import BeautifulSoup
import asyncio

async def scrape():
    test = []
    r = requests.get(coin_desk)
    soup = BeautifulSoup(r.text, features='xml') 
    title = soup.find_all('title')[2]
    await asyncio.sleep(2)
    for x in title:
        test.append(x)
        print(test)

if name == 'main':

try:
    loop = asyncio.new_event_loop()
    asyncio.set_event_loop(loop)
    loop.run_until_complete(scrape())
except (KeyboardInterrupt, SystemExit):
    pass

If i use

run_forever()

instead of

run_until_complete(scrape())

nothing gets printed out, it just runs forever and skips the function it seems.

CodePudding user response：

The async routine (scrape) was never placed into the event loop.

You can add it with

loop.create_task(routine)

See: What does asyncio.create_task() do?
