import tkinter as tk
from tkcalendar import DateEntry
from openpyxl import load_workbook

window = tk.Tk()
window.title("daily logs")
window.grid_columnconfigure(1,weight=1)
window.grid_rowconfigure(1,weight=1)

# labels

tk.Label(window, text="Failed date").grid(row=4, sticky="W", pady=20, padx=20)
