Check if clients are online with ips stored in json [SOLVED]

[AlphaInc]

No. You must read the ip addresses from the json file one by one, and for each address test if it responds.

from subprocess import call, DEVNULL
import platform
import json
import os


def folder():
    path = os.getcwd()
    newPath = path + "/tmp"
    os.mkdir(newPath)

def ping(host_or_ip: str) -> bool :
    """ping(): execute one ping to host_or_ip.
    Returns True if host_or_ip responded,
    else False.
    """
    if platform.system().lower() == "windows":
        countoption = "/n"
    else:
        countoption = "-c"
    return not call(["ping", countoption, "1", host_or_ip],
                    stdout=DEVNULL, stderr=DEVNULL)

responding_hosts = 0
with open("clients.json") as f:
    data = json.load(f)
    for i in data:
        print(f"pinging: {i['ip']}")
        if ping(i["ip"]):
            responding_hosts += 1

print(f"Number of responding hosts: {responding_hosts}")
if responding_hosts > 0 :
    folder()

Okay nice, this worked great!
Sorry, but I have one last question. I tried to check for two different json files (one contains a list of IPs which should be offline and one which should be online) but I'm running into some problems once again:

#!/usr/bin/env python3

#Imports
from subprocess import call, DEVNULL
import platform
import json
import os

#IP Configuration
responding_clients1 = 0
responding_clients2 = 0

#Folder Creation
def folder():
    path = os.getcwd()
    newPath = path + "/tmp"
    os.mkdir(newPath)

#Pinp Configuration
def ping(host_or_ip: str) -> bool :
    if platform.system().lower() == "windows":
        countoption = "/n"
    else:
        countoption = "-c"
    return not call(["ping", countoption, "1", host_or_ip],
                    stdout=DEVNULL, stderr=DEVNULL)

#Clients1 Check
with open("clients1.json") as f1:
    data1 = json.load(f1)
    for i in data1:
        if ping(i["ip"]):
            responding_clients1 += 1

#Clients2 Check
with open("clients2.json") as f2:
    data2 = json.load(f2)
    for i in data2:
        if ping(i["ip"]):
            responding_clients2 += 1

#ToDo
if responding_clients1 > 0 :
    if responding_clients2 == 0:
        folder()

#End
sys.exit()

And I get this error message:

Traceback (most recent call last):
