How to change the text of a Label in PyQt5 from another thread (QThread)?

Question

PyQt

I am writing a server part for a PC remote control program. I decided to make an interface design in PyQt5,
brought the server launch to a separate thread. And I need to derive a variable from the server class with IP and PORT for connection to show it in the interface! How can I do that? (Design made in Qt Desinger)

import socket
import webbrowser

from PyQt5 import QtCore, QtGui, QtWidgets
from PyQt5.QtCore import QThread

class Control(QThread):
    def __init__(self):
        super(Control, self).__init__()
        self.value = 0

    sig = QtCore.pyqtSignal()

    def run(self):
        HOST = socket.gethostbyname_ex(socket.gethostname())[-1][-1]
        PORT = 6677

        #print(HOST)
        with socket.socket(socket.AF_INET, socket.SOCK_STREAM) as s:
            s.bind((HOST, PORT))
            s.listen()
            while True:
                conn, addr = s.accept()
                while True:
                    data = conn.recv(1024).decode('utf-8').lower()
                    print(data)

Answer 1

sig = QtCore.pyqtSignal(str, int)
self.sig.emit(HOST, PORT)
self.control.sig.connect(self.on_signal)

def on_signal(self, host, port):
    self.some_label.setText(host)
