How I created a QR Code Generator in Python

This will be a short article of how I created a simple QR Code Generator in Python

For this step you need to use the qrcode library: https://pypi.org/project/qrcode/

One of the very first steps I did after creating my projects folder is created a virtual environment. A virtual environment in Python is just another separated workspace on your computer where you can install your packages to run Python Projects.

Since I'm on Mac the command is

python3 -m venv venv

The next step would be to activate the virtual machine

source venv/bin/activate

To deactivate a virtual environment you will need to type:

deactivate

Next step would be to install the qrcode package

pip install qrcode

In your Python file make sure you import the qrcode module

import qrcode

In my code I have created two inputs which I store it into a variable called data and filename. The Strip() method Remove spaces at the beginning and at the end of the string:

data = input('Enter a text or URL ').strip()
filename = input('Enter the filename ').strip()

Next here we go into the QR module and create the QR Code object

qr = qrcode.QRCode(box_size=10, border=4)

qr.add.data(data)

image = qr.make_image(fill_color = 'black', back_color = 'white')

image.save(filename)

print(f'QR Code saved as {filename}')

This code you can run on the terminal and it will create a QR code with any URL you choose
