Explore error correction levels in QR codes to enhance scannability.

Creating Custom QR Codes with Python

Introduction to QR Code Customization

We're going to dive into crafting custom QR codes. The initial steps will focus on creating colored QR codes, which allows you to make the visually distinct. Later, we'll embed logo images to provide branding. This entire process utilizes python programming, opening the door for beginner level python learners. Understanding and working through this beginner python project provides learners with a deep understanding of how python code and images function. This project allows you to not only customize your QR codes, but to also deeply understand python programming.

Key Concepts Covered:

  • QR Code Generation: Using the qrcode library.
  • Color Customization: Changing foreground and background colors.
  • Image Embedding: Adding a logo to your QR code.
  • Error Correction: Ensuring reliable scanning.
  • Python Basics: Setting up variables and writing efficient code.

Step-by-Step Guide: Creating a Colored QR Code

First, let's create colored QR codes. We start by importing the necessary qrcode library. Then define our data. For example 'edtech by meera', which creates a variable to hold information for the QR code.

Code Snippet:

import qrcode
data = "edtech by meera"

Next, a variable is created that utilizes the QR code function to generate the QR code itself. This also involves adjusting the dimensions for the generated QR code. As the code is adjusted the dimensions will be adjusted in order to fit with a better fit for a visually appealing graphic.

Code Snippet:

qr = qrcode.QRCode(version=1, box_size=10, border=4)

Now you want to ensure the data that was just assigned is implemented into the project. This is achieved through using the .add_data function. The data string must be passed through the .add_data function in order for the content to be included. And finally, using the make function and applying a fit equals true parameter the QR code is finished.

Code Snippet:

qr.add_data(data)
qr.make(fit=True)

The last step that needs to be addressed is assigning new colors and then saving the newly customized image. This is done as follows:

Code Snippet:

img = qr.make_image(fill_color="green", back_color="yellow")
img.save("edtechbymeera.png")

In the code block above fill_color refers to the color of the QR codes body, while the back_color refers to the background color.

By following these steps, you can customize the look of your QR code, allowing you to use a QR code with specific branding. Using color alone allows for simple easy customizations to your code.
