Python 3

Fix the code so the user can not select a day after than today's date and it show a warning "Select a correct date"

Code:

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


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

# labels
tk.Label(window, text="Bar code").grid(row=0, sticky="W", pady=20, padx=20)
tk.Label(window, text="Products failed").grid(row=1, sticky="W", pady=20, padx=20)
tk.Label(window, text="Money Lost").grid(row=2, sticky="W", pady=20, padx=20)
tk.Label(window, text="sold by").grid(row=3, sticky="W", pady=20, padx=20)
tk.Label(window, text="Failed date").grid(row=4, sticky="W", pady=20, padx=20)

# entries
barcode = tk.Entry(window)
product = tk.Entry(window)
money = tk.Entry(window)

# arraging
barcode.grid(row=0, column=1)
product.grid(row=1, column=1)
money.grid(row=2, column=1)

options = tk.StringVar(window)
options.set("Choose one value")  # default value
soldData = tk.OptionMenu(window, options, "Peter", "John", "Mary", "Jonatan", "Steve")
soldData.grid(row=3, column=1)
cal = DateEntry(window, width=12, background='darkblue', foreground='white', borderwidth=2)
cal.grid(row=4, column=1)

def readValue():
    excel_barcode = barcode.get()
    excel_product = product.get()
    excel_money = money.get()
    excel_sold = options.get()
    if excel_sold.strip() == 'Choose one value':
        messagebox.showwarning("Error", "Please select a value for sold by")
        return
    date = datetime.now()
    print(date)
    data = [excel_barcode, excel_product, excel_money, excel_sold, date]
    workbook = load_workbook("dailylog.xlsx")
    worksheet = workbook.worksheets[0]
    worksheet.append(data)
    workbook.save("dailylog.xlsx")
    cleardate()


def cleardate():
    barcode.delete(0, 'end')
    product.delete(0, 'end')
    money.delete(0, 'end')
    options.set("Choose one value")  # default value
    today = datetime.now()
    cal.set_date(today)


# button to trigger actions
button = tk.Button(text="SUBMIT", command=readValue).grid(row=5, pady=20, padx=20)
button = tk.Button(text="CLEAR", command=cleardate).grid(row=5, column=1, pady=20, padx=20)
window.geometry("500x400")
window.mainloop()

Please find the fixed code:

import tkinter as tk
from tkcalendar import DateEntry
from openpyxl import load_workbook
from tkinter import messagebox
from datetime import date, datetime

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

# labels
tk.Label(window, text="Bar code").grid(row=0, sticky="W", pady=20, padx=20)
tk.Label(window, text="Products failed").grid(row=1, sticky="W", pady=20, padx=20)
tk.Label(window, text="Money Lost").grid(row=2, sticky="W", pady=20, padx=20)
tk.Label(window, text="sold by").grid(row=3, sticky="W", pady=20, padx=20)
tk.Label(window, text="Failed date").grid(row=4, sticky="W", pady=20, padx=20)

# entries
barcode = tk.Entry(window)
product = tk.Entry(window)
money = tk.Entry(window)

# arraging
barcode.grid(row=0, column=1)
product.grid(row=1, column=1)
money.grid(row=2, column=1)

options = tk.StringVar(window)
options.set("Choose one value") # default value
soldData = tk.OptionMenu(window, options, "Peter", "John", "Mary", "Jonatan", "Steve")
soldData.grid(row=3, column=1)
cal = DateEntry(window, width=12, background='darkblue', foreground='white', borderwidth=2)
cal.grid(row=4, column=1)

def readValue():
    excel_barcode = barcode.get()
    excel_product = product.get()
    excel_money = money.get()
    excel_sold = options.get()
    cal_date = cal.get()
    #date string converted to proper date format
    cal_date_format = datetime.strptime(cal_date,'%m/%d/%y').date()
  
    if excel_sold.strip() == 'Choose one value':
        messagebox.showwarning("Error", "Please select a value for sold by")
        return
    #date validation
   if cal_date_format > date.today():
        messagebox.showwarning("Error", "Select a correct date")
        return

    data = [excel_barcode, excel_product, excel_money, excel_sold, cal_date_format]
    workbook = load_workbook("dailylog.xlsx")
    worksheet = workbook.worksheets[0]
    worksheet.append(data)
    workbook.save("dailylog.xlsx")
    cleardate()

def cleardate():
    barcode.delete(0, 'end')
    product.delete(0, 'end')
    money.delete(0, 'end')
    options.set("Choose one value") # default value
    today = datetime.now()
    cal.set_date(today)

# button to trigger actions
button = tk.Button(text="SUBMIT", command=readValue).grid(row=5, pady=20, padx=20)
button = tk.Button(text="CLEAR", command=cleardate).grid(row=5, column=1, pady=20, padx=20)
window.geometry("500x400")
window.mainloop()

Output:
