Getting Started with Tkinter

To give you an idea of how Tkinter works, let’s start with a simple example. We are going to create a basic window with a label and a button that changes the label’s text when clicked.

import tkinter as tk

# Define function to change the label text, color, and font size
def on_button_click():
    label.config(text="Welcome to codeloop.org", fg="red", font=("Helvetica", 16))

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

# Create a label and a button
label = tk.Label(root, text="Welcome to Tkinter")
button = tk.Button(root, text="Click Me", command=on_button_click)

# Arrange the label and button on the window
label.pack(pady=10)
button.pack(pady=10)

# Run the application event loop
root.mainloop()

import tkinter as tk

# Define function to change the label text, color, and font size

def on_button_click():

label.config(text="Welcome to codeloop.org", fg="red", font=("Helvetica", 16))

# Create the main window

root = tk.Tk()

root.title("Tkinter Introduction Example")

# Create a label and a button

label = tk.Label(root, text="Welcome to Tkinter")

button = tk.Button(root, text="Click Me", command=on_button_click)

# Arrange the label and button on the window

label.pack(pady=10)

button.pack(pady=10)

# Run the application event loop

root.mainloop()

Run the code and this will be the result
