object oriented programming solve 2 quetions

9 Lab 8 - Graphical User Interface (GUI) The assignments for this week are to understand the use of tkinter modules to create GUI in Python. 9.1 Assignment 1 1. Create the following window using the tkinter module in Python. The button Quit closes the window, and the button Show prints the first name and last name entered in the Entry boxes. First Name Last Name Quit Show 2. Create the following window using the tkinter module in Python. The button Quit closes the window, and the button Show prints the sum of the two numbers entered in the Entry boxes, if the entered values are not numbers, then raise an appropriate exception in a MessageBox. Enter Num 1: Enter Num 2 The Sum is Quit Show 3. Create the following window using tkinter module in Python.

Answer 1

Here is the answer for your question in Python Programming Language.

Question 1

CODE :

import tkinter as tk """Creates Window and sets its dimensions""" window = tk.Tk() window.geometry("350x200") """Variables to store values from entry boxes""" firstName = tk.StringVar() lastName = tk.StringVar() """Method to quit window""" def quitWindow(): window.destroy() """Method to show name""" def show(): """Gets first and last names and stores them in 'name'""" name = firstName.get() + " " + lastName.get() """Displays name""" resultLabel = tk.Label(window, text="Name : " + name) resultLabel.grid(row = 3, column = 0) """Resets entry boxes""" firstName.set("") lastName.set("") """Required GUI components""" firstNameLabel = tk.Label(window, text="First Name") firstNameEntry = tk.Entry(window, textvariable = firstName, width=25, bd=2) lastNameLabel = tk.Label(window, text="Last Name") lastNameEntry = tk.Entry(window, textvariable = lastName, width=25, bd=2) quitBtn = tk.Button(window, text = "Quit", command = quitWindow) showBtn = tk.Button(window, text = "Show", command = show) """Sets positions for GUI Components""" firstNameLabel.grid(row = 0, column = 0) firstNameEntry.grid(row = 0, column = 1) lastNameLabel.grid(row = 1, column = 0) lastNameEntry.grid(row = 1, column = 1) quitBtn.grid(row = 2, column = 0) showBtn.grid(row = 2, column = 1) window.mainloop()

OUTPUT :

tk Х First Name Last Name Quit Show

After entering names,

tk ] X First Name John Last Name Dog Quit Show

After pressing "show"

tk х First Name Last Name Quit Name: John Doe Show
