Python QR Code Decoder | QR Code to text

Motive 

        In our last blog, we created a QR code generated with python so why not a decoder to decode the QRcode without scanning it.

        In our last blog, we created a QR code generated with python so why not a decoder to decode the QRcode without scanning it. 

Project

         Before starting to make a project lets install the necessary modules for this project, pyxbar and pillow.

pip install pyzbar pip install pillow

        Open your cmd and type those codes separately to install pyzbar and pillow and you can learn more about pyzbar here and pillow here.

Let's start by importing the necessary modules for our project:

from pyzbar.pyzbar import decode from PIL import Image

        Now we will create a variable called decode and the take the image of the QR code with the help of pillow and then decode it with pyzbar:

decode = decode(Image.open('Python.png'))

This is the QRcode that we are going to use and it is in the same directory and is called Python.png:

Now that we have decided the image lets try printing it:

print(decode)

By running the code we get this:

[Decoded(data=b'I Love Python', type='QRCODE', rect=Rect(left=63, top=63, width=370, height=370), polygon=[Point(x=63, y=63), Point(x=63, y=431), Point(x=433, y=433), Point(x=431, y=63)])]

But we only the text. So let's find it's location. Here, it in data as binary code. Now let's create another variable called text and the take the first item in that list and then navigating to data:

text = decode[0].data 

Now let's try printing text:

print(text)

But it's in the binary string:

b'I Love Python'

So let's convert it into text like this:
text = decode[0].data.decode('ascii')

Then let's try printing text:
print(text)

Now we got what we wanted:

I Love Python

Full Code

from pyzbar.pyzbar import decode from PIL import Image decode = decode(Image.open('Python.png')) text = decode[0].data.decode('ascii') print(text)
