Loop through list of ip-addresses [SOLVED]

[AlphaInc]

Hello everybody,

I want to use a python script to check if certain ips are still online and if not, i want the system to shut down.
Therefore I have created a list of client ip's and a loop to check every ip if its online or not and then, if all ip's are down, execute a command (in this example it is the command #Command1) and if not, it should execute another command (in this exampe #Command2).

def ip_check():
    hosts = [
    "192.168.180.100",
    "192.168.180.101",
    "192.168.180.102",
    "192.168.180.103",
    "192.168.180.104",
    "192.168.180.105",
    "192.168.180.106"
    ]
   
    for x in hosts:
        host_response = os.system("ping -c 1 " + str(hosts))

    if guest_response == 0:
        #Command1
    else:
        #Command2

The problem is, all i get is this output and I don't know how to fix it:
