How to use stepic.encode()

Question

from PIL import Image
import stepic
img = Image.open ('a.png')
img2 = stepic.encode(img, 'hello world')
img2.show()

Here the code is giving the following error:

TypeError: unsupported operand type(s) for &: 'str' and 'int'

Python 3.6 is used.

Answer 1

had the same problem.. I tested on Python 3.6.6 simply change the line below FROM:

img2 = stepic.encode(img, 'hello world')

TO:

img2 = stepic.encode(img, b'hello world')

you need to pass your data/text as binary
