Python 3.7.10 : Simple example with PyQRCode.

The pyqrcode module is a QR code generator that can automate most of the building process for creating QR codes.
The pypng python library is required to save and upload PNG images.
I had to install them both with the pip utility.
pip install pyqrcode
Collecting pyqrcode

pip install pypng

Let's try some simple examples:
import pyqrcode
url = pyqrcode.create('https://ro.wikipedia.org/wiki/Utilizator:Catalin_Festila', error='H', mode='binary')
url.svg('uca-url.svg', scale=8)
url.eps('uca-url.eps', scale=2)
url.png('code.png', scale=5, module_color=[0, 0, 0, 128], background=[0, 0, 128])
url.show()
print(url.terminal(quiet_zone=1))
This is the result of this source code:
