Write a Python GUI program to create a Combobox with three options using tkinter module.

Sample Solution:

Python Code:

import tkinter as tk
from tkinter import ttk

root = tk.Tk()
my_str_var = tk.StringVar()

my_combobox = ttk.Combobox(
    root, textvariable = my_str_var,
    values=["PHP", "Java", "Python"])

my_combobox.pack()
root.mainloop()

Explanation:

In the exercise above -

• import tkinter as tk - Import the Tkinter library (tkinter)
• from tkinter import ttk – Import the themed Tkinter library (ttk).
• root = tk.Tk() - Create the main Tkinter window (root).
• my_str_var = tk.StringVar() - Create a StringVar (my_str_var) to hold a string variable.
• my_combobox = ttk.Combobox(root, textvariable = my_str_var, values=["PHP", "Java", "Python"]) - Create a Combobox widget (my_combobox) using ttk.Combobox. Associate the StringVar (my_str_var) with the Combobox using textvariable. Set the values that can be selected in the Combobox.
• my_combobox.pack() - Display the Combobox within the main window.
• root.mainloop() - Start the Tkinter main loop to run the GUI application.
