$ pip install PyQRCode pyzbar pillow

import pyqrcode
from pyzbar.pyzbar import decode
from PIL import Image

data = pyqrcode.create('hi')
#the data format is import
data.png('qrcode_img.png', scale=2)
#qr code image is created
decoded = decode(Image.open('qrcode_img.png'))
#your output console print contains a list of info encoded in your qrcode
print(decoded)

import pyqrcode
qr = pyqrcode.create("HELLO WORLD")
qr.png("code.png", scale=6)

import qrtools
qr = qrtools.QR()
qr.decode("code.png")
print qr.data
u'HELLO WORLD'
