#PYTHON QR CODE READER LIBRARY HOW TO#

This tutorial will use the PyPNG, OpenCV, and pyqrcode libraries. We will use the pip package manager to install the libraries. After creating the virtual environment, we can install the packages.

If you don’t know how to create and use virtual environments in Python, then follow our guide on creating virtual environments in python. It is first recommended to create a virtual environment to install and use the python libraries, which will separate the libraries’ installation process. Let us begin our installation process for all the required libraries. See the following installation procedure to install pyqrcode and all the other required libraries. It has a class with the name QRCode that can be used to create a QRCode object, followed by using this object to add data and generate the QR Code. It follows all the standards for creating QR codes from the text. In python, we have a module named pyqrcode, which eases creating QR codes in python. It is also recommended to use an IDE like the open-source Visual Studio Code for writing the Code. To follow this tutorial, you must have python installed in your system.

In this tutorial, we see how to generate and read QR codes programmatically using Python.

Due to QR codes’ ability to store more data and fast readability, it gained huge popularity over the bar codes, which are composed of black bars and white spaces in a single dimension. QR codes or Quick Response Codes is a two-dimensional bar code consisting of some black squares into a white background.
