Introduction

In this tutorial, we will be creating a dictionary application using the Tkinter library in Python. Tkinter is a standard Python library for creating GUI applications, and it is included in most Python distributions. This tutorial will cover the basics of creating a GUI with Tkinter, as well as adding functionality to our dictionary application.

Installing Tkinter

Before we can begin creating our dictionary application, we first need to make sure that Tkinter is installed on our system. If you are using a version of Python that is older than 3.1, Tkinter may not be included by default, and you will need to install it. You can check if Tkinter is installed by running the following command in your command prompt or terminal:

import tkinter

If Tkinter is installed, you should not see any error messages. If you do see an error message, you can install Tkinter by running the following command:

pip install tkinter

Creating the GUI

Now that we have Tkinter installed, we can start creating our GUI. We will begin by importing the Tkinter module and creating a new Tkinter window.

import tkinter as tk

root = tk.Tk()
root.title("Dictionary")

Next, we will create a label that will be used to display the definition of a word.

definition_label = tk.Label(root, text="Enter a word to find its definition.")
definition_label.pack()

We will also create an entry widget that will be used to enter the word that we want to look up.

lookup_button = tk.Button(root, text="Look Up")
lookup_button.pack()

Finally, we will create a button that will be used to trigger the dictionary lookup.

lookup_button = tk.Button(root, text="Look Up")
lookup_button.pack()

Adding Functionality

Now that we have our basic GUI set up, we can start adding functionality to our application. We will begin by importing the json module, which will be used to parse the data from the dictionary file.

import json

Next, we will create a function that will be called when the “Look Up” button is clicked. This function will read the word from the entry widget, look it up in the dictionary file, and display the definition in the label.

def lookup_word():
    with open("dictionary.json") as dictionary_file:
        dictionary_data = json.load(dictionary_file)
    word = word_entry.get()
    definition = dictionary_data.get(word, "Word not found.")
    definition_label.config(text=definition)

Finally, we will associate the lookup_word function with the “Look Up” button.

lookup_button.config(command=lookup_word)

Full Code Application

import tkinter as tk
import json

root = tk.Tk()
root.title("Dictionary")

definition_label = tk.Label(root, text="Enter a word to find its definition.")
definition_label.pack()

word_entry = tk.Entry(root)
word_entry.pack()

lookup_button = tk.Button(root, text="Look Up")
lookup_button.pack()

def lookup_word():
    with open("dictionary.json") as dictionary_file:
        dictionary_data = json.load(dictionary_file)
    word = word_entry.get()
    definition = dictionary_data.get(word, "Word not found.")
    definition_label.config(text=definition)

lookup_button.config(command=lookup_word)

root.mainloop()

Dictionary.json Sample

{
    "hello": "A greeting used to initiate a conversation or to express goodwill.",
    "goodbye": "A farewell remark.",
    "python": "A programming language that is widely used for web development, data analysis, artificial intelligence, and more.",
    "tkinter": "A python library for creating GUI applications",
    "seo": "Search Engine Optimization, the practice of increasing the quantity and quality of traffic to a website from search engines."
}
