Python Language A minimal tkinter Application


tkinter is a GUI toolkit that provides a wrapper around the Tk/Tcl GUI library and is included with Python. The following code creates a new window using tkinter and places some text in the window body.

Note: In Python 2, the capitalization may be slightly different, see Remarks section below.

import tkinter as tk

# GUI window is a subclass of the basic tkinter Frame object
class HelloWorldFrame(tk.Frame):
    def __init__(self, master):
        # Call superclass constructor
        tk.Frame.__init__(self, master)
        # Place frame into main window
        # Create text box with "Hello World" text
        hello = tk.Label(self, text="Hello World! This label can hold strings!")
        # Place text box into frame
        hello.grid(row=0, column=0)

# Spawn window
if __name__ == "__main__":
    # Create main window object
    root = tk.Tk()
    # Set title of window
    root.title("Hello World!")
    # Instantiate HelloWorldFrame object
    hello_frame = HelloWorldFrame(root)
    # Start GUI
