Python – UwU text convertor GUI using Tkinter

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)


# Driver code
if __name__ == "__main__" :

    # Create a GUI window
    root = Tk()

    # Set the background colour of GUI window
    root.configure(background = 'light green')

    # Set the configuration of GUI window (WidthxHeight)
    root.geometry("400x350")

    # set the name of tkinter GUI window
    root.title("Converter")

    # Create Welcome to Morse Code Translator label
    headlabel = Label(root, text = 'Welcome to UwU text converter',
                      fg = 'black', bg = "red")

    # Create a "Text " label
    label1 = Label(root, text = " Text ",
                 fg = 'black', bg = 'dark green')

    # Create a "UwU Text " label
    label2 = Label(root, text = "UwU Text",
                   fg = 'black', bg = 'dark green')


    # grid method is used for placing
    # the widgets at respective positions
    # in table like structure .
    headlabel.grid(row = 0, column = 1)
    label1.grid(row = 1, column = 0)
    label2.grid(row = 3, column = 0)


    # Create a text area box
    # for filling or typing the information.
    text1_field = Text(root, height = 5, width = 25, font = "lucida 13")
    text2_field = Text(root, height = 5, width = 25, font = "lucida 13")

    # padx keyword argument used to set padding along x-axis .
    # pady keyword argument used to set padding along y-axis .
    text1_field.grid(row = 1, column = 1, padx = 10, pady = 10)
    text2_field.grid(row = 3, column = 1, padx = 10, pady = 10)


    # Create a Convert Button and attached
    # with convert function
    button1 = Button(root, text = "Convert into UwU text", bg = "red", fg = "black",
                                command = convert)

    button1.grid(row = 2, column = 1)

    # Create a Clear Button and attached
    # with clearAll function
    button2 = Button(root, text = "Clear", bg = "red",
                     fg = "black", command = clearAll)

    button2.grid(row = 4, column = 1)

    # Start the GUI
    root.mainloop()
