My QML file is this

import QtQuick 2.12
import QtQuick.Window 2.12
import QtQuick.Controls 2.12

Window {
    id:window
    visible: true
    width: 500
    flags: Qt.AlignLeft
    height: 375
    color: "transparent"
    title: qsTr("Nidgets")
    Timer{
        interval:100
        running: true
        repeat: true
        onTriggered: {
            time.text = Qt.formatDateTime(new Date(), "hh:mm A")
            date.text = Qt.formatDateTime(new Date(), "yyyy MMMM dd")
        }
    }

    Item {
        id: element1
        x: 0
        y: 0
        width: 200
        anchors.fill: parent
        height: 200
        focus: true
        Keys.onPressed: {
            if ((event.key === Qt.Key_F11) && (event.modifiers & Qt.ControlModifier)){
                if(window.flags == Qt.FramelessWindowHint)
                    window.flags = 0
                else
                    window.flags = Qt.FramelessWindowHint
            }
        }

        Text {
            id: date
            x: 310
            y: 205
            color: "#ffffff"
            text: Qt.formatDateTime(new Date(), "yyyy MMMM dd")
            font.pixelSize: 24
        }

        Text {
            id: time
            x: 74
            y: 86
            color: "#ffffff"
            anchors.centerIn: parent
            text: Qt.formatDateTime(new Date(), "hh:mm A")
            anchors.verticalCenterOffset: -45
            anchors.horizontalCenterOffset: 35
            font.pointSize: 75

        }


    }
}

and here is the python file

import sys
from PyQt5.QtCore import QObject, QUrl
from PyQt5.QtWidgets import QApplication
from PyQt5.QtQuick import QQuickView
from PyQt5.QtQml import QQmlApplicationEngine
from threading import Thread
import os
import importlib

if __name__ == '__main__':
    myApp = QApplication(sys.argv)

    engine = QQmlApplicationEngine()
    context = engine.rootContext()
    context.setContextProperty("main", engine)

    engine.load('main.qml')

    win = engine.rootObjects()[0]
    win.show()

    sys.exit(myApp.exec_())

thanks
