how to check ping using python?

Question

I am trying to make my Discord bot ping a server and reply “{time} ms” but failed. I searched google but all the codes are just replying “Network Active” or “Network Error”.

Here is my code (Copied on Stack Overflow)(I use linux as server so I use “-c 1 ”

import os
@commands.command()
async def ping(self, ctx, ip):
    host = ip
    response = os.system(“ping “ + “-c 1 ” + host)
    if response == 0:
        ping_status = “Network Active”
    else:
        ping_status = “Network Error”
    await ctx.send(ping_status)

@bereal the codes can run but i hope it can reply "{time} ms" — Adrian0811

you can use this code to get times returned by ping.

import re
import subprocess

output = subprocess.check_output(['ping', '-c', '5', 'google.com'])
output = output.decode('utf-8').splitlines()
times = []
for o in output:
    m = re.search(r'time=([\d]+\.?[\d]*)', o)
    if m:
        times.append(m.group(1))
print(times)

you should save output of ping, and then extract times with the aim of regex.

Considering that the OP is using asyncio, create_subprocess_exec might be a better choice.
