Not able to connect Websockets through Kite API -

Hi
can any one help me to correct or suggest how to connect websocket for personal analysis (i have valid API with 500 points as well)

from kiteconnect import KiteConnect, KiteTicker

API_KEY = "d9x8olz0kXXXXXXXX"
API_SECRET = "ubj7daxn49ge777jXXXXXXXXXX"

kite = KiteConnect(api_key=API_KEY)

# Paste your current request_token manually here
request_token = "cHSAElN14rfU2b1gq5vCdXXXXXXXXXX"

data = kite.generate_session(request_token, API_SECRET)
access_token = data["access_token"]

kite.set_access_token(access_token)

kws = KiteTicker(API_KEY, access_token)

def on_connect(ws, resp):
print("???? WS Connected")
ws.subscribe([738561])
ws.set_mode(ws.MODE_FULL, [738561])

def on_ticks(ws, ticks):
print("???? Ticks:", ticks)

kws.on_connect = on_connect
kws.on_ticks = on_ticks

kws.connect(threaded=True)

while True:
time.sleep(1)
