Introduction PyQt6 is a set of Python bindings for Qt6, one of the most powerful frameworks for building graphical user interfaces (GUIs). With PyQt6, you can create professional desktop applications that run on Windows, macOS, and Linux — all using Python.

layout = QGridLayout() layout.addWidget(QLabel("Name:"), 0, 0) layout.addWidget(QLineEdit(), 0, 1) layout.addWidget(QLabel("Email:"), 1, 0) layout.addWidget(QLineEdit(), 1, 1) Override built-in event handlers or connect signals.

from PyQt6.QtWidgets import QMessageBox def show_info(): QMessageBox.information(window, "Title", "This is an info message.") You can design UIs visually using Qt Designer (included with Qt tools) and load .ui files in Python:

sys.exit(app.exec())

pip install PyQt6 Verify the installation:

window.setLayout(layout) window.show()
