Python Tkinter Restaurant Billing System Tutorial

Welcome to our tutorial on creating a restaurant billing system using Python Tkinter!

Introduction

Python Tkinter is a great tool for creating GUI applications. In this tutorial, we will create a simple restaurant billing system that allows users to select items from a menu, enter quantities, and calculate the total bill.

Step 1: Creating the GUI

First, we will create a simple GUI with labels, entry fields, and buttons for the users to interact with. We will also define functions for handling user input and calculating the total bill.

Code Example:

        
            import tkinter as tk
            
            root = tk.Tk()
            root.title("Restaurant Billing System")
            
            # Create labels, entry fields, and buttons here
            
            root.mainloop()
        
    

Step 2: Creating the Menu

Next, we will define a menu with items and prices that users can select from. We will use a dictionary to store the menu items and prices, and display them in a listbox or dropdown menu for the users to choose from.

Code Example:

        
            # Define the menu items and their prices
            menu = {
                "Pizza": 10,
                "Burger": 5,
                "Pasta": 8
            }
            
            # Display the menu items in a listbox or dropdown menu
        
    

Step 3: Calculating the Total Bill

Finally, we will create a function to calculate the total bill based on the items selected and their quantities. We will iterate through the user input and use the menu dictionary to look up the prices of the selected items.

Code Example:

        
            # Calculate the total bill based on the user input
            total = 0
            for item, quantity in user_input.items():
                total += menu[item] * quantity
                
            # Display the total bill to the user
