create a notepad app using python
Here is an example of how you could create a Notepad application in Python:

```python
import os
from tkinter import *

root = Tk()
notebook = Notebook(root)
# Add widgets to the notebook window
Label(text="Note Title").grid(row=0, column=0)
Entry(width=20).grid(row=1, column=0)
Button(text='Save', command=lambda: save_to_file('notes.txt')).grid(row=2, column=0)
# Create file handler for saving notes to disk
def save_to_file(filename):
    with open(os.path.join('.', filename), 'w+b') as fh:
        fh.write("\n".join([note.get("1.0", END) for note in notebook.pages]))

notebook.pack()

# Run program
root.mainloop()```
