Developing the Program

Although QR codes can store various types of data, the easiest way to begin is by encoding a URL. First, we need to install and import the necessary libraries to generate a custom QR code and save it as a PNG file.

To start, install the libraries using pip. If you face any issues with pip, consider using pip3:

pip install pyqrcode

pip install pypng

Next, import these libraries into your Python script:

import pyqrcode

import png

Now, we will prompt the user for input so the QR code can direct users to a specific URL:

file_name = input('Enter the name of the QR code: ')

website = input('Enter the link to your website: ')

We can then store this input in a variable named qr_data and generate the QR code using the pyqrcode library:

qr_data = website

qr_code = pyqrcode.create(qr_data)

Having created the QR code, we now need to save it as a PNG file, which can be utilized in various contexts. We'll also include a print statement to confirm the successful creation of the QR code and PNG file:

file_name_png = file_name + '.png'

qr_code.png(file_name_png, scale=4)

print("Generated QR code")

Upon executing the program, you will generate a QR code. Scan it to explore more about my work. Here’s an example linked to Aviral Mehrotra's LinkedIn profile.

import pyqrcode

import png

file_name = input('Enter the name of the QR code: ')

website = input('Enter the link to your website: ')

qr_data = website

qr_code = pyqrcode.create(qr_data)

file_name_png = file_name + '.png'

qr_code.png(file_name_png, scale=4)

print("Generated QR code")

This concise yet effective Python script demonstrates how swiftly you can create QR codes for sharing information. The concepts discussed here can be seamlessly integrated into larger projects.
