Decoding QR code in python

Question

I am trying to read QR codes using python3. I've found different solutions that depend on using qrtools.

I've also tried to download it using pip3 or apt-get. Then I've tried to install it from sources, tried to install zbar lib which it use to work, but I had multiple errors.

I've also tried to download and use it in python2, and it works successfully. And I want to ask, can I use it in python3, or it is impossible?

Looking at qrtools docs it seems Python3 is supported. I suggest you file a bug report to the developers with a full error description included. — Hubert Grzeskowiak, Nov 04 '15 at 10:35

I found the answer to the question: zbar QR code reader in python 3 in google. There is an library that does this. Download the follow library in pip install. ZBar it self is only for python 2, but the zbarlight also for python 3.

https://pypi.python.org/pypi/zbarlight

edit: My answer would be usefull: How to use Python Pip install software, to pull packages from Github?

Thanks for response, but I think the biggest problem is to install zbar library. – Oleg Klimenko Nov 04 '15 at 13:04
You don't need then zbar library but the zbarlight library in python 3 – Martijn van Wezel Nov 04 '15 at 13:23
After install, I try to import it, but have this: ImportError: No module named 'zbarlight._zbarlight' is it normal, or I am doing something wrong ? – Oleg Klimenko Nov 04 '15 at 14:33
yes, you doing something wrong, did you do : pip install zbarlight – Martijn van Wezel Nov 04 '15 at 14:43
Wow, I don't know why, but when I tried it in console using python3 it gave me an exception. When I used it in PyCharm, its ok. So, thank you very much @Martijn van Wezel – Oleg Klimenko Nov 04 '15 at 14:47

I have used pyzbar for reading my QR codes in Python3.

Installation:

brew install zbar
pip install pyqrcode
pip install pyzbar

And for reading the code:

from PIL import Image
from pyzbar.pyzbar import decode


result = decode(Image.open('sample.png'))
print(result)
