Point of Sale Python Tkinter – Billing System

Punto De Venta Python Tkinter – Billing System

In this tutorial, we will create a billing system using Python’s Tkinter library. Tkinter is a GUI toolkit that allows you to create applications with a graphical user interface.

Step 1: Set up your environment

Before we start coding, make sure you have Python installed on your computer. You can download Python from the official website (https://www.python.org/downloads/).

Next, install Tkinter by running the following command in your terminal:

pip install tkinter

Step 2: Create a new Python file

Open your favorite text editor and create a new Python file. Save it as billing_system.py.

Step 3: Import the necessary libraries

Now, let’s import the necessary libraries for our billing system:

from tkinter import *

Step 4: Create the main window

Next, let’s create the main window for our billing system:

root = Tk()
root.title("Punto De Venta Python Tkinter - Billing System")
root.geometry("800x600")

Step 5: Create the user interface

Now, let’s create the user interface for our billing system. You can customize it according to your needs. Here’s an example layout:

# Label for product name
product_name_label = Label(root, text="Product Name:")
product_name_label.pack()

# Entry field for product name
product_name_entry = Entry(root)
product_name_entry.pack()

# Label for product price
product_price_label = Label(root, text="Product Price:")
product_price_label.pack()

# Entry field for product price
product_price_entry = Entry(root)
product_price_entry.pack()

# Button to add product
add_product_button = Button(root, text="Add Product")
add_product_button.pack()

# Listbox to display products
products_listbox = Listbox(root)
products_listbox.pack()

# Label for total price
total_price_label = Label(root, text="Total Price: $0.00")
total_price_label.pack()

# Button to calculate total price
calculate_total_button = Button(root, text="Calculate Total")
calculate_total_button.pack()

Step 6: Define functions

Next, let’s define the functions for adding products and calculating the total price:

def add_product():
    product_name = product_name_entry.get()
    product_price = float(product_price_entry.get())
    products_listbox.insert(END, f"{product_name} - ${product_price}")

def calculate_total():
    total_price = 0
    for i in range(products_listbox.size()):
        product = products_listbox.get(i)
        price = float(product.split(" - ")[1][1:])
        total_price += price
    total_price_label.config(text=f"Total Price: ${total_price:.2f}")

Step 7: Connect functions to buttons

Lastly, let’s connect the functions to the buttons we created earlier:

add_product_button.config(command=add_product)
calculate_total_button.config(command=calculate_total)

# Run the main loop
root.mainloop()

And that’s it! You have created a billing system using Python’s Tkinter library. You can further customize the user interface and add more functionality to suit your needs.

I hope you found this tutorial helpful. Happy coding!
