In this post, we will see how to create a QR code generator in Python.

For creating the QR code generator we will be using pyqrcode module of python. This module needs to be installed explicitly on your system because this module does not come up with python already.
For installation:

pip install pyqrcode

Run the above-given command in your command line for installing the given python module.

Steps to follow:

• First, importing the pyqrcode module.
• Taking string as input for which QR code needs to create.
• Create QR object using pyqrcode.create().
• Save QR object in different formats like SVG or png using respective methods.

Let’s see the Implementation:

# Importing given module to this program
import pyqrcode
  
# String which QR code need to create
input_string = "https://www.biochemithon.in/"
  
# Generating QR code object
# using create() class of
# pyqrcode module
qr_code = pyqrcode.create(input_string) 
  
# Save this qr_code object as a svg file  
# at given location with scale 4 
# using svg() method of qr_code object.
# Scale attribute determine the dimension
# of svg image created.
qr_code.svg(r"C:\Users\hp\OneDrive\Desktop\mywebsite.svg",
            scale = 4)

# Save this qr_code object as a png file  
# at given location with scale 4 
# using png() method of qr_code object.

# For using this png method,
# you must install pypng module first
qr_code.png(r"C:\Users\hp\OneDrive\Desktop\mywebsite.png",
            scale = 4)

Output:

 svg image: 

 png image:

Note: you must install pypng module before using png() method of qr_code object.

For installation:

pip install pypng

Run the above-given command in your command line for installing the given python module.
