Advanced Python: GUI (Graphical User Interface)

Goal

• Create your own programs with windows

Step 1: Using tkinter

import tkinter as tk

# Create window
window = tk.Tk()
window.title("My Program")

# Add label
label = tk.Label(window, text="Hello World")
label.pack()

# Start program
window.mainloop()

Explanation:

• tk.Tk() → creates a new window
• window.title() → sets the window title
• tk.Label → displays text inside the window
• pack() → displays the element
• window.mainloop() → starts the event loop; the window stays open

Task

• Create a window with a button
• When the button is clicked, display some text (e.g., in a Label)

Button Example

import tkinter as tk

def show_text():
    label.config(text="Button was clicked!")

window = tk.Tk()
window.title("Button Example")

label = tk.Label(window, text="Hello World")
label.pack()

button = tk.Button(window, text="Click me!", command=show_text)
button.pack()

window.mainloop()
