Python for GUI Development: Tkinter & PyQt 🖥️🐍

Python provides multiple libraries for Graphical User Interface (GUI) development, with Tkinter and PyQt being the most popular.

🔹 Tkinter – Built-in, lightweight, easy to use
🔹 PyQt – Feature-rich, powerful, modern UI

Let’s explore both! 🚀

1️⃣ Tkinter – Built-in GUI Toolkit 🎨
🔹 Tkinter comes pre-installed with Python.
🔹 Great for simple desktop applications.
🔹 Provides basic widgets like buttons, labels, and text fields.

Basic Tkinter App

import tkinter as tk

# Create main window
root = tk.Tk()
root.title("Tkinter Example")

# Create a label
label = tk.Label(root, text="Hello, Tkinter!", font=("Arial", 16))
label.pack(pady=10)

# Create a button
def on_click():
label.config(text="Button Clicked!")

button = tk.Button(root, text="Click Me", command=on_click)
button.pack(pady=5)

# Run the application
root.mainloop()
✅ Run the script – A simple window with a button will appear!

✅ Key Features:

✔ Comes with Python (no extra installation needed)
✔ Lightweight and easy to learn
✔ Ideal for small GUI apps

2️⃣ PyQt – Advanced GUI Framework 🏗️

🔹 PyQt is a powerful, professional GUI framework.
🔹 Based on Qt (a popular cross-platform GUI toolkit).
🔹 Supports modern UI design with advanced widgets.

Installing PyQt

pip install pyqt6
Basic PyQt App

from PyQt6.QtWidgets import QApplication, QWidget, QLabel, QPushButton, QVBoxLayout
import sys

class MyApp(QWidget):
def __init__(self):
super().__init__()

# Window properties
self.setWindowTitle("PyQt Example")
self.setGeometry(100, 100, 300, 200)

# Create layout
layout = QVBoxLayout()

# Create label
self.label = QLabel("Hello, PyQt!", self)
layout.addWidget(self.label)

# Create button
button = QPushButton("Click Me")
button.clicked.connect(self.on_click)
layout.addWidget(button)

self.setLayout(layout)

def on_click(self):
self.label.setText("Button Clicked!")

# Run the application
app = QApplication(sys.argv)
window = MyApp()
window.show()
sys.exit(app.exec())

✅ Run the script – A modern, interactive GUI window will appear!

✅ Key Features:
✔ Supports advanced widgets & layouts
✔ Cross-platform (Windows, macOS, Linux)
✔ Ideal for large-scale GUI applications

3️⃣ Tkinter vs. PyQt – When to Choose What?
