Age Calculator App using Tkinter - part 3 | GUI Python Programming Certification Training | Uplatz

Python Tkinter is a standard GUI (Graphical User Interface) toolkit for Python. It provides a set of tools and widgets that allow developers to build desktop applications with a graphical user interface. Tkinter is included with most Python installations and does not require any additional installation.

Here is an example of an Age Calculator App using Python's Tkinter library:

import tkinter as tk
from datetime import date

def calculate_age():

# Create the window
root = tk.Tk()

# Create the labels and entries
day_label = tk.Label(root, text="Day:")
day_entry = tk.Entry(root, width=5)

month_label = tk.Label(root, text="Month:")
month_entry = tk.Entry(root, width=5)

year_label = tk.Label(root, text="Year:")
year_entry = tk.Entry(root, width=8)

# Create the button and result label
calculate_button = tk.Button(root, text="Calculate", command=calculate_age)

result_label = tk.Label(root, text="")

# Start the main loop

(Note - for the above code replace LESS-THAN SIGN with a left angled bracket in the actual code)

This program creates a GUI window using the Tkinter library. It prompts the user to enter a birthdate in day, month, and year format. When the user clicks the "Calculate" button, the program calculates the age based on the birthdate and the current date using the date class from the datetime module and displays the result in a label.

The main components of a Tkinter application are windows, frames, buttons, labels, text boxes, and other widgets. These widgets can be organized in a hierarchical structure to create complex user interfaces. Tkinter also provides support for event-driven programming, which allows developers to write code that responds to user actions such as button clicks and mouse movements.

One of the main advantages of Tkinter is its simplicity and ease of use. It has a small learning curve and is easy to understand for developers who are new to GUI programming. Tkinter also provides good cross-platform support, which means that applications built with it can run on different operating systems such as Windows, Mac OS, and Linux.

Tkinter is a great choice for developers who want to build simple and straightforward desktop applications with a graphical user interface using Python. Its simplicity and cross-platform support make it a popular choice for beginners and experienced developers alike.
