    PyQt5 is a powerful Python library for creating desktop applications with graphical user interfaces (GUIs) using the Qt toolkit. It allows you to build professional-looking applications with ease. In this guide, we'll walk through creating a simple "Hello World" application using PyQt5.

    Setting Up Your Environment

    First, ensure you have PyQt5 installed. You can install it using pip:

    pip install PyQt5

    Creating Your First PyQt5 Application

    Let's create a basic PyQt5 application that displays a window with a "Hello World" message. Follow these steps:

    1. Import Required Modules: Import the necessary PyQt5 modules.

    2. Create the Application Object: Initialize the QApplication object.

    3. Create the Main Window: Create a QWidget object to serve as the main window.

    4. Show the Window: Display the window using the show() method.

    5. Run the Application: Start the event loop using the exec_() method.

    Here is the complete code for your first PyQt5 application:

    from PyQt5.QtWidgets import QApplication, QWidget, QLabel, QVBoxLayout
    import sys

    # Step 1: Create the application object
    app = QApplication(sys.argv)

    # Step 2: Create the main window
    window = QWidget()
    window.setWindowTitle('Hello World App')

    # Step 3: Add a label to the window
