To start our application script, create a folder called ABQ data entry and a file inside it called data_entry_app.py.
We'll start with the following boilerplate code:
import tkinter as tk
from tkinter import ttk
# Start coding here
class Application(tk.Tk):
    """Application root window"""
if __name__ == "__main__":
    app = Application()
    app.mainloop()
Running this script should give you a blank Tk window.
