Python - UwU text convertor GUI using Tkinter

Last Updated : 12 Jun, 2021

Prerequisites :Introduction to tkinter | UwU text convertor

Python offers multiple options for developing a GUI (Graphical User Interface). Out of all the GUI methods, Tkinter is the most commonly used method. It is a standard Python interface to the Tk GUI toolkit shipped with Python. Python with Tkinter outputs the fastest and easiest way to create GUI applications. Now, it’s up to the imagination or necessity of a developer, what he/she wants to develop using this toolkit.

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.

Below is what the GUI looks like:

Let’s create a GUI based uwu-text-convertor application that can convert text input given by the user into uwu text.

Below is the implementation :

Python3

# import all functions from the tkinter  
from tkinter import *

# 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 convert into UwU text 
def convert() :

    # get a whole input content from text box
    # ignoring \n from the text box content
    input_text = text1_field.get("1.0", "end")[:-1]
    
    # the length of the input text 
    length = len(input_text) 
      
    # variable declaration for the output text 
    output_text = '' 
      
    # check the cases for every individual character 
    for i in range(length): 
          
        # initialize the variables 
        current_char = input_text[i] 
        previous_char = None
          
        # assign the value of previous_char 
        if i > 0: 
            previous_char = input_text[i - 1] 
          
        # change 'L' and 'R' to 'W' 
        if current_char == 'L' or current_char == 'R': 
            output_text += 'W'
          
        # change 'l' and 'r' to 'w' 
        elif current_char == 'l' or current_char == 'r': 
            output_text += 'w'
          
        # if the current character is 'o' or 'O' 
        # also check the previous character 
        elif current_char == 'O' or current_char == 'o': 
            if previous_char == 'N' or previous_char == 'n' or previous_char == 'M' or previous_char == 'm': 
                output_text += "yo"
            else: 
                output_text += current_char 
          
        # if no case match, write it as it is 
        else: 
            output_text += current_char 
  
    text2_field.insert('end -1 chars', output_text)
