Python how to retrieve data in array

Question

First I am not sure if this is an array. But this is pyzbar decoding an image of a QRcode

>>> from pyzbar.pyzbar import decode
>>> from PIL import Image
>>> barcode = decode(Image.open('qr111.png'))
>>> print(barcode)
[Decoded(data='812', type='QRCODE', rect=Rect(left=1166, top=306, width=336, height=336), polygon=[Point(x=1166, y=306), Point(x=1166, y=642), Point(x=1502, y=642), Point(x=1502, y=306)])]

I want to retrieve specifically the value "812" of data, how do I do it? I tried print(barcode[Decoded(data)]) to no avail.

Try print(barcode[0].data). Decoded looks like name of type in that case, and outer [..] looks like a list. — yeputons, Commented May 29, 2018 at 9:14

This will get you what you want:

barcode[0].data

It's all in the source code.
