I need help error when I replace input with string

Question

I need help with fixing an error that occurs when I try to replace input in a puzzle solver code with a premade string as it doesn't work if I change it. This is not my code the original code can be found at https://github.com/CYBERDEVILZ/artificial-intelligence. I hope someone is able to help me with this problem thanks for your time. Solved by https://stackoverflow.com/users/1883316/tim-roberts I have no idea how to select his answer as the answer so if anyone knows how could you tell me.

Answer 1

If you are trying to take input from your Str variable instead of from input, you might notice that you never use Str anywhere in your code. You need to replace this:

puzzle = enterBoard(puzzle)

with this:

puzzle = list(map(int,Str.split()))

Or, you could just set

puzzle = [0,1,3,2,4,5,6,7,8]

and comment out the call to enterBoard.
