It contains a grid of black squares on a white background, which can be read by any imaging device such as a camera, and processed to extract the required data from the patterns that are present in the horizontal components of the image.
QR Codes with Python: Tutorial
In this section, I will take you through a tutorial on how to generate QR codes with Python. To generate QR Codes with Python you need to install only one Python library for this task:
- pip install pyqrcode
Now let’s see how to create a QR Code with Python programming language:
import pyqrcode
from pyqrcode import QRCode
# String which represent the QR code
s = "https://www.youtube.com/channel/UCeO9hPCfRzqb2yTuAn713Mg"
# Generate QR code
url = pyqrcode.create(s)
# Create and save the png file naming "myqr.png"
url.svg("myyoutube.svg", scale = 8) 
I hope you liked this article on how to generate a QR Code with Python. Feel free to ask your valuable questions in the comments section below.
what is the use of scale = 8
Just to make the qr code larger and smaller, you can manipulate this number
I tried this code pycharm but nothing i could see
you will get to see an image saved in the directory you are working
where exactly in the directory in pycharm
In the same directory where your Python file is.
Thanks for sharing Aman. This is cool. I will surely try it out.
great
