Prerequisites : Introduction to tkinter | SpongeBob Mocking Text Generator

Python offers multiple options for developing a GUI (Graphical User Interface). Out of all the GUI methods, Tkinter is the most commonly used method. Python with Tkinter outputs the fastest and easiest way to create GUI applications. In this article, we will learn how to create a SpongeBob Mocking Text Generator GUI application using Tkinter, with a step-by-step guide.

To create a Tkinter :

Importing the module – tkinter
Create the main window (container)
Add any number of widgets to the main window.
Apply the event Trigger on the widgets.

The GUI would look like below:

Let’s create a GUI-based SpongeBob Mocking Text Generator application that can generate SpongeBob Text from the input given by the user.

Below is the implementation :

Python3

# import all functions from the tkinter  
from tkinter import *

# import the random library 
import random

# Function to clear both the text areas
def clearAll() :
    # whole content of text area  is deleted 
    text1_field.delete(1.0, END)
    text2_field.delete(1.0, END)

# Function to Generate SpongeBob Mocking Text
def generate() :

    # get a whole input content from text box
    # ignoring \n from the text box content
    input_text = text1_field.get("1.0", "end")[:-1]
    
    # variable declaration for the output text 
    output_text = "" 
      
    # check the cases for every individual character 
    for char in input_text: 
          
        # check if the character is an alphabet 
        if char.isalpha(): 
              
            # convert to upper case 
            if random.random() > 0.5: 
                output_text += char.upper() 
                  
            # convert to lower case 
            else: 
                output_text += char.lower() 
          
        # if character is not and alphabet 
        # add it as it is 
        else: 
            output_text += char 
  
    text2_field.insert('end -1 chars', output_text)
