For this task you can invoke the append function that you have implemented in the .qml through QMetaObject.invokeMethod() as shown below:

main.py

counter = 0

def onTimeout(obj):
    global counter
    value = {"lesson": str(counter), "subject": "PE", "day": QDate.longDayName(1 + counter % 7)}
    QMetaObject.invokeMethod(obj, "append", Q_ARG(QVariant, value))
    counter += 1


if __name__ == '__main__':
    app = QApplication(sys.argv)
    w = QQuickWidget()
    w.setSource(QUrl('main.qml'))
    timer = QTimer()
    timer.timeout.connect(lambda: onTimeout(w.rootObject()))
    timer.start(1000)
    w.show()
    sys.exit(app.exec_())

main.qml

import QtQuick 2.0

Rectangle {
    width: 640
    height: 480

    function append(newElement) {
        scheduleModel.append(newElement)
    }
    ListModel {
        id: scheduleModel
    }

    ListView {
        anchors.fill: parent
        id: scheduleList
        model: scheduleModel
        delegate: scheduleItem

        section.property: "day"
        section.delegate: sectionDelegate
    }


    Component {
        id: scheduleItem
            Row {
                spacing: 15
                Text {
                    text: lesson
                }
                Text {
                    text: subject
                }
        }
    }

    Component {
        id: sectionDelegate
            Text {
                id: label
                text: section
            }
    }
}
