Last update on December 21 2024 07:48:14 (UTC/GMT +8 hours)

Write a Python GUI program to create two buttons exit and hello using tkinter module.

On pressing hello button print the text “Tkinter is easy to create GUI” on the terminal.

Sample Solution:

Python Code:

import tkinter as tk   

def write_text():
    print("Tkinter is easy to create GUI!")

parent = tk.Tk()
frame = tk.Frame(parent)
frame.pack()

text_disp= tk.Button(frame, 
                   text="Hello", 
                   command=write_text
                   )

text_disp.pack(side=tk.LEFT)

exit_button = tk.Button(frame,
                   text="Exit",
                   fg="green",
                   command=quit)
exit_button.pack(side=tk.RIGHT)

parent.mainloop()

Explanation:

In the exercise above -

import tkinter as tk - Import the Tkinter library (tkinter).
def write_text(): - Define a function (write_text) to print a message.
parent = tk.Tk() - Create the main Tkinter window (parent).
frame = tk.Frame(parent) - Create a Frame widget (frame) within the main window.
text_disp= tk.Button(frame, text="Hello", command=write_text) - Create a "Hello" button (text_disp) that calls the write_text function when clicked.
exit_button = tk.Button(frame, text="Exit", fg="green", command=quit) - Create an "Exit" button (exit_button) to close the application when clicked.
exit_button.pack(side=tk.RIGHT) - Display the buttons within the Frame (frame).
parent.mainloop() - Start the Tkinter main loop to run the GUI application.
