循环检测服务器某个端口是否开放

脚本如下：

import socket
import datetime
import time
 
def check_port(host, port):
    try:
        socket.create_connection((host, port), timeout=1).close()
        return True
    except socket.error as e:
        return False

host = '166.166.166.24'
port = 5236
while True:
    with open('test.log', 'a') as file:
        if check_port(host, port):
            file.write(str(datetime.datetime.now()) + f" Port {port} on {host} is open.\n")
        else:
            file.write(str(datetime.datetime.now()) + f" Port {port} on {host} is closed or unreachable.\n")
    file.close()
    time.sleep(10)
