Question

Python 3

Fix the code so if the user enter the same bar code more than three times, it shows a warning message indicating that the product was already tested 3 times and it reached the limits

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)
tk.Label(window, text="Working product").grid(row=5, sticky="W", pady=20, padx=20) #Working product label

# 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)

#option menu for working product Yes/No
optionsWorkingProduct = tk.StringVar(window)
optionsWorkingProduct.set("Choose working product")  # default value
workingProduct = tk.OptionMenu(window, optionsWorkingProduct, "Yes", "No")
workingProduct.grid(row=5, column=1)
barcode_ls=[]


def readValue():
    excel_barcode = barcode.get()
    excel_product = product.get()
    excel_money = money.get()
    excel_sold = options.get()
    excel_workingProduct= optionsWorkingProduct.get()

    if excel_sold.strip() == 'Choose one value':
        messagebox.showwarning("Error", "Please select a value for sold by")
        return
    if excel_workingProduct.strip() == 'Choose working product': #check for the not selected working product
        messagebox.showwarning("Error", "Please select a value for working product")
        return

    date = datetime.now()
    print(date)
    data = [excel_barcode, excel_product, excel_money, excel_sold, date, excel_workingProduct]
    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
    optionsWorkingProduct.set("Choose working product") # default value set to the working product
    today = datetime.now()
    cal.set_date(today)


# button to trigger actions
button = tk.Button(text="SUBMIT", command=readValue).grid(row=6, pady=20, padx=20)
button = tk.Button(text="CLEAR", command=cleardate).grid(row=6, column=1, pady=20, padx=20)
window.geometry("500x500")
window.mainloop()
