Python Client: "kws.connect()" is not triggering the infinite loop, plesae help

I have a small learning program to print the tick data of one stock. It runs perfectly fine and prints the LTP, but curser stops after printing one LTP, seems like the "kws.connect()" is not triggering the infinite loop.

it could be some other reasons as well, please some experts in this forum check this and tell me what is missing in this simple code

#######################################
from kiteconnect import KiteConnect
from kiteconnect import KiteTicker

#-------------------------login------------------------------------#

api_k = "xxxxx" # api_key
api_s = "yyyyy" # api_secret
access_token = "zzzzz"

def get_login(api_k, api_s): # log in to zerodha API panel
global kws, kite
kite = KiteConnect(api_key=api_k)

kite.set_access_token(access_token)
kws = KiteTicker(api_k, access_token)

get_login(api_k, api_s)

#-------------------------login------------------------------------#

def on_ticks(ws, ticks):
print(ticks)

def on_connect(ws, response):
ws.subscribe([177665])
ws.set_mode(ws.MODE_LTP, [177665])

kws.on_ticks = on_ticks
kws.on_connect = on_connect
kws.connect()
