QR is short for Quick Response, and they are named so because they can be read quickly by a cell phone. They are used to take information from transitory media and put it on your cell phone. In this article, I will walk you through a tutorial on how to generate QR codes with Python.
What is a QR code?
QR codes are used to encode and decode the data into a machine-readable form. The use of camera phones to read two-dimensional barcodes for various purposes is currently a popular topic in both types of research and practical applications.Ā

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 letās 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.
Sir how is install pip install pyqrcode in my laptop
go to your command prompt, and open the folder where you mostly save your Python files then write this command and hit enter. You can also search about it on Youtube as āhow to install a Python moduleā
Thanks for sharing Aman. This is cool. I will surely try it out.
great
No module named āpyqrcodeā i am getting a error
run pip install pyqrcode in your terminal.
Can we scan this QR Code ?
print(āYou are Great Sir I am following your Projects for practise. Thank you so muchā)
yes you can, thanks for appreciatingš¤
awesome work and it is useful to many young programmers
thanks, keep visiting
Thanks for all of these examples my friend and the time youāve taken to break down each of your codes. Not all heroes wear capes š
thanksš¤ keep visitingš
sir my program is susseccfully run but QR CODE is not generate in the directory
it will be saved on the same folder where your Python file is
šš
really appreciate on your effort for these exercise. it make python really fun to me.
I update the code like below:
import qrcode
from qrcode import QRCode
s=āwww.kensington.comā
url=qrcode.make(s)
url.save(ākensingtonqrcode.pngā)
