Вызов функции Python с Qml

QML, PyQt5

Всем здравствуйте.

Незамысловатая задача появилась у меня - вызвать функцию Python с Qml.
Смотрел уроки на этом сайте, но что-то я не понимаю. Сверял код Qt C++, вроде как всё также, но не работает и прошу помощи у вас

Вот код:

main.py

# This Python file uses the following encoding: utf-8

from PySide2.QtGui import QGuiApplication
from PySide2.QtQml import QQmlApplicationEngine
from PyQt5.QtCore import QObject, pyqtSignal, pyqtSlot
from bs4 import BeautifulSoup
import sys
import os
import requests
import time

s = requests.Session()
class Calculator(QObject):
    def __init__(self):
        QObject.__init__(self)

    takeFunc = pyqtSignal()

    @pyqtSlot()
    def result(self, text):
        while True:
            t=s.get("http://v.meni.mobi")
            soup = BeautifulSoup(t.text, 'html.parser')
            self.text=soup.find("div", class_="footer_share").find("a").get("href")
            print(text)
            time.sleep(1)


if __name__ == "__main__":
    app = QGuiApplication(sys.argv)
    engine = QQmlApplicationEngine()

    calculator = Calculator()
    engine.rootContext().setContextProperty("calculator", calculator)

    engine.load(os.path.join(os.path.dirname(__file__), "main.qml"))

    if not engine.rootObjects():
        sys.exit(-1)
    sys.exit(app.exec_())

main.qml

import QtQuick 2.15
import QtQuick.Window 2.15
import QtQuick.Extras 1.4
import QtQuick.Controls 2.3

Window {
    width: 640
    height: 480
    visible: true
    title: qsTr("Hello World")

    Connections {
        target: calculator

        // Обработчик сигнала сложения
        onResult: {

        }
    }

 Button {
     id: button
     x: 207
     y: 167
     text: qsTr("Button")
     onClicked: calculator.result
 }
}

При компиляции такие ошибки ползут:

Буду очень благодарен советам или помощи

Чтобы onResult в QML подключилось к чему-то в Python, нужно чтобы result было сигналом, а у вас это слот.
В качестве сигнала определено takeFunc и в данном случае в QML должно работать так

Connections {
    target: calculator

    // Обработчик сигнала сложения
    onTakeFunc: {

    }
}
