An expense calculator is a handy tool that helps users track their spending and manage their finances by inputting expenses and calculating total expenditures, providing valuable insights into their budget management. #PYTHON import tkinter as tk from tkinter import ttk from tkinter import Entry, Label, Button, Listbox, Scrollbar import calendar

Initialize an empty list to store expenses

Create the main application window

root = tk.Tk() root.title("Expense Tracker")

Input fields and labels

date_label = Label(root, text="Date (DD/MM/YYYY):") date_label.pack() date_entry = Entry(root) date_entry.pack()

desc_label = Label(root, text="Description:") desc_label.pack() desc_entry = Entry(root) desc_entry.pack()

amount_label = Label(root, text="Amount (₹):") amount_label.pack() amount_entry = Entry(root) amount_entry.pack()

Buttons

record_button = Button(root, text="Record Expense", command=record_expense) record_button.pack()

edit_button = Button(root, text="Edit Expense", command=edit_expense) edit_button.pack()

delete_button = Button(root, text="Delete Expense", command=delete_expense) delete_button.pack()

generate_button = Button(root, text="Generate Report", command=generate_report) generate_button.pack()

Expense list

expense_list_label = Label(root, text="Expenses:") expense_list_label.pack()

expense_listbox = Listbox(root, selectmode=tk.SINGLE, width=40) expense_listbox.pack()

Add a scrollbar for the expense list

scrollbar = Scrollbar(root) scrollbar.pack(side=tk.RIGHT, fill=tk.Y) expense_listbox.config(yscrollcommand=scrollbar.set) scrollbar.config(command=expense_listbox.yview)

Result label

result_label = Label(root, text="") result_label.pack()

root.mainloop()
