How we can run local ntp server using ntplib library in Python

Question

Can someone help me regarding the Local NTP server in Python. The python code is below:

import ntplib
from time import ctime
while True:
 try:
  c = ntplib.NTPClient()
  response = c.request(host='192.168...',port=2947)
  print(response)
  print(ctime(response.tx_time))
 except Exception as e:
    print(e)

When i run this code, the output returns no response received from 192.168....
