Async possible?

Async possible?

if i want to ping many websites at once (using requests library) it takes a long time.. is it possible that it first pings web1, then withoutnwaiting for output, pings 2 then waits till both gets pinged?

Current code: how do i change it?

import requests, sleep
websites = ["web1","web2"]
while True:
  for i in websites:
    try:
      requests.get(i,timeout=1)
    except:
      print('timeout error')
  time.sleep(0.5)

Takes approx 0.5 to 0.8 or even 1 second to complete 1 loop of while true excluding time.sleep

I would try threading, that way you can run a whole bunch of threads.

import threading
import requests
import time # not sleep

def ping(website):
  try:
    requests.get(website, timeout=1)
  except:
    print(f"Timeout error with website {website}")

while True:
  for i in websites:
    thread = threading.Thread(target=ping, args=[i])
    thread.start()
    thread.join()
  time.sleep(0.5)

This way it won't wait for that thread to be done, it will just move on to creating another thread without waiting for that ping to be made.

@InvisibleOne thanks!

Is threading better thatn asyncio? @InvisibleOne

@InvisibleOne wait..... thread.join() waits. Is there anything wrong?

I didn't mean to put that in there, this code was adapted from another program I wrote and I just left that there. @QuantumCodes

I haven't really used asyncio so I don't know which one is better @QuantumCodes

K @InvisibleOne

You can use threading, like this:

from threading import Thread

websites = []

def ping_website(link):
  # add code to ping website

for i in websites:
  t = Thread(target=ping_website, args=(link))
  t.start()

also never ever ping a website every half second -- that's on the verge of making the website crash. Make it do every 5 minutes.

@Coder100 oh.. mat1 pinger pings every 5 secs, so i didnt think this will happen xD thx!

try using asyncio

@QuestionableNS ? Any sample code?

@QuantumCodes
import asyncio
async def main():
while True:
print('Hello ...')
await asyncio.sleep(1)
print('... World!')
asyncio.run(main())

i will try and tell. Thx @QuestionableNS
