Python使用PyCharm创建一个简单的Qt Quick应用程序-hello_world_quick.py（读取qml文件方式）

"""Create a Simple Quick Application"""
import sys
from pathlib import Path

from PySide6.QtGui import QGuiApplication
from PySide6.QtQml import QQmlApplicationEngine


# 打开文件，读取文件，并返回文件内容
def read_file(file_path):
    """
    :param file_path:文件全路径
    功能：打开文件，读取文件，并返回文件内容。
    """
    assert file_path.exists(), f'文件<{file_path}>必须存在才是！！！'
    with open(file_path, 'r', encoding='utf-8') as f:
        return f.read()


if __name__ == "__main__":
    app = QGuiApplication(sys.argv)
    engine = QQmlApplicationEngine()
    QML = read_file(Path(__file__).with_suffix('.qml'))  # 读取.qml文件
    engine.loadData(QML.encode('utf-8'))
    if not engine.rootObjects():
        sys.exit(-1)
    exit_code = app.exec()
    del engine
    sys.exit(exit_code)

hello_world_quick.qml文件内容：

    readonly property list<string> texts: ["Hallo Welt", "Hei maailma",
                                    "Hola Mundo", "Привет мир", "您好，世界！"]

    function setText() {
        var i = Math.round(Math.random() * 3)
        text.text = texts[i]
    }

    ColumnLayout {
