从 csv 读取并检查 ip 地址可达性

Question

I am reading the IP addresses from a CSV and then check if the IP addresses are reachable store the IP addresses in the list, please advise what is it that I am doing here is wrong?

addr = []

def ip_reachable(addr):
    result = subprocess.run(f"ping -n 3 -w 1 {addr}", stdout=subprocess.DEVNULL)
    if result.returncode == 0:
        return result.returncode, addr


with open("test.csv") as file_name:
    read_csv_file = csv.DictReader(file_name)
    for index_col in read_csv_file:
        if ip_reachable(index_col["column_1"]):
            addr.append(ip_reachable)



print(addr)

Answer 1

Instead of:

addr.append(ip_reachable)

Try this:

addr.append(index_col['column_1'])

I believe you want to store the address itself ie in column1 and not the method ip_reachable .
