You're misunderstanding what a rotation is if you say there are 23 of them. Have you read the wikipedia link?

There are 23 rotations of string 'bsjq'. Array ["bsjq", "qbsj", "sjqb", "twZNsslC", "jqbs"], wich contain only 5 elements can't include all 23 rotations. I can't anderstand why this case return true.

Check my code for a more optimized version of your def get_sum

Which is smaller?

29917 or 201997
26945 or 209645

Yes of course you need to know the color of the field :D 1 is black and 0 is white.

I took a example QRCode. The field will be always different, you only have to understand the way you go through the field. (Like the red arrow)

The init in all som cases are set to the number 0

Right, no problem with that. The parameter init is what it is. Nobody said it should be a[0].

They are equal according to the description.

Not an issue. Read the description properly.

+ Your code is funny XD

+ Are you summing it up correctly?

Your function is returning None. And the tests try to sort that, that's the error about. See what it does here: http://pythontutor.com/visualize.html#mode=edit

Is it normal for that error to come up when theres not even any code written

Instead of pass it could say return (0, 1), like this:

def two_sum(numbers, target):
    # start coding!
    return (0, 1)

The indices of these items should then be returned in a tuple like so: (index1, index2).

Where is your tuple?

Still, 3.8 should be enforced or set as default, otherwise we'll see this popping up again and again.

Switch to Python 3.8.
