Decoding a QR code means finding the value, number, text or link behind the QR code. There are many ways to decode a QR code used by your smartphone cameras, which helps you scan a QR code while making online payments. So if you want to learn how to decode a QR code, this article is for you. In this article, I will take you through a tutorial on how to decode a QR code using Python.
Decode a QR Code using Python
I recently shared an article on creating a QR code using Python. If you want to learn about creating a QR code, you can learn more about it from here. To decode a QR code, you need an image of a QR code. You can use any QR code image for this tutorial, or you can create your QR code.
For decoding QR codes using Python, you need to install two Python libraries in your Python environment; pyzbar and pillow. You can install both these libraries by executing the commands mentioned below in your command prompt or terminal:
- pip install pyzbar
- pip install pillow
Now below is how you can write a program to decode a QR code using Python:
from pyzbar.pyzbar import decode
from PIL import Image
decocdeQR = decode(Image.open('instagram.png'))
print(decocdeQR[0].data.decode('ascii'))https://www.instagram.com/the.clever.programmer/
In the code above, I’m using a QR code image that redirects people to my Instagram account. So this program gives the link of my Instagram account in the output.
Summary
So this is how you can decode QR codes using the Python programming language. Decoding QR codes means finding the value, number, text or link behind the QR code. I hope you liked this article on decoding QR codes using Python. Feel free to ask valuable questions in the comments section below.
