We need ZBar tool to read QR code. ZBar is an open source software suite for reading bar codes from various sources, such as video streams, image files and raw intensity sensors. It supports many popular symbologies (types of bar codes) including EAN-13/UPC-A, UPC-E, EAN-8, Code 128, Code 39, Interleaved 2 of 5 and QR Code.

Other Python module installation

pip install pypng

pip install pyqrcode

pip install pillow

pip install pyzbar

Code

from pyzbar.pyzbar import decode
from PIL import Image

d = decode(Image.open("codesnail-qr-code.png"))
# print(d)
print(d[0].data.decode())

#Follow @code_snail

Here we read codesnail-qr-code.png
