I'll guide you through the process of creating a QRcode generator in this article. I'm assuming you have your IDE installed and ready to go. In this article, we will work with two Python modules.

What is QR code?

QR stands for "quick response." A QR code is a sort of barcode that encodes information as a sequence of pixels in a square-shaped grid and can be quickly read by a digital device. QR codes are widely used to monitor information about items in a supply chain, and they are frequently utilized in marketing and advertising efforts since many smartphones have built-in QR scanners.

How to install the required module

Before we begin writing code, we must ensure that we have pyqrcode and pypng installed on our system. Copy and paste the following lines into your terminal to correctly install these modules.

Official documentation can be found here

pip install pyqrcode

Official documentation can be found here

pip install pypng

Let's get started now that you've successfully installed the modules listed above.

Source Code and Explanation

#these imports the necessary module
import pyqrcode
import png

# users are asked to input the link to be to be converted to QRCODE
link = input("Enter link: ")

# used to create the qrcode
qr_code = pyqrcode.create(link)

# this line of code is run if the above code worked
print("Voiala! qrcode created." )

# this line of code saves the qrcode in png format
qr_code.png("qrName.png", scale=5)
print("QRcode generated!")

The above source code will generate a QR code with a customized name. The first step is to import pyqrcode and import png

To generate the QR Code, we need the user's input, which is saved in the variable "link" in the source code. We call the create function from pyqrcode and pass "link" to it; we then save this in another variable called "qr_code."

Congratulations! If you have understood it to this stage, you have successfully created a QR code. Finally, to save our QR code in.png format, we add .png to activate the function from the previously imported module png, give our QR code a name, and select the desired scale.

Summary

Hurray! We have successfully built the QR Code generator in Python. In this article, we learned how to accept links from users, convert them to QR codes with the PyQRcode module, and save them as pngs with the PNG module. I hope you enjoyed building this project.
