Build a Text Editor Using Python

Hello coder, welcome to the codewithrandom blog. In this article, we will build a text editor using Python built-in Tkinter library.  Text editor an essential tool for developers, writers, and anyone who works with text-based documents. A text editor provides a simple interface for entering and editing text and offers features such as syntax highlighting, auto-completion, and indentation.

Tkinter : Tkinter is a standard Python library for creating graphical user interfaces (GUIs). It provides a set of tools for creating windows, buttons, menus, and other widgets.

To create a text editor using python in Tkinter, we need to perform the following steps:

For this text editor using python project, we need to install Tkinter  Gui. You can install these packages in your terminal.

$ pip install tk

step 1: open any python code Editor.

step 2: Importing the Required Modules.

from tkinter import *

import tkinter.filedialog

step 3: Copy the code for text editor using Python, which I provided Below in this article, and save it in a file named “main.py” (or any other name you prefer).

step 4: Run this  python file main.py to start the text editor.

from tkinter import *
import tkinter.filedialog


class TextEditor:

    @staticmethod
    def quit_app(event=None):
        root.quit()

    def open_file(self, event=None):

        txt_file = tkinter.filedialog.askopenfilename(parent=root, initialdir="./examples")

        if txt_file:

            self.text_area.delete(1.0, END)

            with open(txt_file) as _file:

                self.text_area.insert(1.0, _file.read())

                root.update_idletasks()

    def save_file(self, event=None):
        file = tkinter.filedialog.asksaveasfile(mode='w')

        if file != None:
            data = self.text_area.get('1.0', END + '-1c')

            file.write(data)
            file.close()

    def __init__(self, root):
        self.text_to_write = ""

        root.title("TextEditor")

        root.geometry("600x550")

        frame = Frame(root, width=600, height=550)

        scrollbar = Scrollbar(frame)

        self.text_area = Text(frame , width=600, height=550, yscrollcommand=scrollbar.set, padx = 10, pady=10)

        scrollbar.config(command=self.text_area.yview)

        scrollbar.pack(side="right", fill="y")

        self.text_area.pack(side="left", fill="both", expand=True)

        frame.pack()

        the_menu = Menu(root)

        file_menu = Menu(the_menu, tearoff=0)
        file_menu.add_command(label="Open", command=self.open_file)
        file_menu.add_command(label="Save", command=self.save_file)

        file_menu.add_separator()
        file_menu.add_command(label="Quit", command=self.quit_app)

        the_menu.add_cascade(label="File", menu=file_menu)
        root.config(menu=the_menu)


root = Tk()
text_editor = TextEditor(root)
root.mainloop()
