लेखन त्रुटि: प्रकाशित () 2 स्थितीय तर्क लेता है लेकिन 3 दिए गए थे

इसलिए मैं एक एमक्यूटीटी प्रकाशक पर काम कर रहा हूं और एक पब क्लास बनाना चाहता हूं। मुझे एक समान प्रश्न यहां मिला, लेकिन मुझे नहीं पता कि यह मेरी समस्या का कैसे अनुवाद करता है।

यह मेरा कोड है:

def send_on_sensor(q, topic, delay, pub):

    while q.empty is not True:
        payload = json.dumps(q.get())
        pub.publish(payload)
        time.sleep(delay)


class Pub:
    def __init__(self, MQTT_BROKER, MQTT_TOPIC):
        self.MQTT_BROKER = MQTT_BROKER
        self.MQTT_TOPIC = MQTT_TOPIC
        self.mqttc = mqtt.Client()

        self.mqttc.on_connect = self.on_connect
        self.mqttc.publish = self.publish

        # Connect automatically on the creation of the object, but disconnect manually
        self.connect()

    def on_connect(self, client, userdata, flags, rc):
        print("Connecting to {}. Connection returned result: {}".format(self.MQTT_BROKER, rc))
        self.mqttc.subscribe(self.MQTT_TOPIC)

    def publish(self, MQTT_MSG):
        self.mqttc.publish(self.MQTT_TOPIC, MQTT_MSG)

    def connect(self):
        self.mqttc.connect(self.MQTT_BROKER)

    def disconnect(self):
        self.mqttc.disconnect()

मुझे यह त्रुटि मिलती है:

Exception in thread Thread-4:
Traceback (most recent call last):
  File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/threading.py", line 917, in _bootstrap_inner

    self.mqttc.publish(self.MQTT_TOPIC, MQTT_MSG)
TypeError: publish() takes 2 positional arguments but 3 were given

यहां वास्तव में क्या समस्या है और मैं इसे कैसे ठीक करूं?
