how to stop run_forever and do other jobs, then continue running in python websocket?

Question

"my question is how to stop websocket running when the bid_sirt has changed, I want to make another calculation and then come back restart websocket"

bid_sirts = [1,1]

def ws_message(ws, message):
    global bid_sirt    
    bid_sirt= json.loads(message)["result"]["bids"][0]   
    bid_sirts.append(bid_sirt)


def ws_open(ws):
    ws.send(json.dumps({
        "time": int(time.time()),
        "channel": "spot.order_book",
        "event": "subscribe",  # "unsubscribe" for unsubscription
        "payload": ["BTC_USDT", "10", "100ms"]
    }))
def ws_close(ws):
    print("ws closed")

def ws_orderbook():
    ws = websocket.WebSocketApp("wss://api.gateio.ws/ws/v4/", on_open=ws_open, on_message=ws_message,on_close=ws_close)
    ws.keep_running = False
    if bid_sirts[-2] != bid_sirts[-1]:
        ws.keep_running = True
        print("ws closed")`enter code here`
