Welcome folks today in this blog post we will be making a windows notepad in tkinter using python. This will be a complete notepad where you can perform the following operations on it

create new files

save files

And now we need to install python on our system.

And after this we need to install tkinter on your system by executing the following command

pip install tkinter

And after this make a notepad.py file and copy paste the following code

notepad.py

from tkinter import *
import tkinter as tk
from tkinter.scrolledtext import ScrolledText
from tkinter import filedialog
from tkinter import messagebox,font
from tkinter import ttk
from datetime import datetime
import webbrowser
