Giving Wrong Solution

[ThisMonkeysGoneToHeaven]

Hey Tim,
try this matrix for board in the solver (text) file. this is giving incorrect solution. you can verify correct answer if you wish from https://anysudokusolver.com/.

correct solution

board = [
[1, 0, 0, 0, 4, 0, 0, 0, 0],
[0, 9, 2, 6, 0, 0, 3, 0, 0],
[3, 0, 0, 0, 0, 5, 1, 0, 0],
[0, 7, 0, 1, 0, 0, 0, 0, 4],
[0, 0, 4, 0, 5, 0, 6, 0, 0],
[2, 0, 0, 0, 0, 4, 0, 8, 0],
[0, 0, 9, 4, 0, 0, 0, 0, 1],
[0, 0, 8, 0, 0, 6, 5, 2, 0],
[0, 0, 0, 0, 1, 0, 0, 0, 6]
]

your code solution is :

Yep, got me the wrong answer too.

#Check Col

for i in range(0, len(bo)):

    if bo[i][pos[1]] == num and pos[1] != i:
       return False

Here is this problem - it should be pos[0] != i instead of pos[1]

[uripeled2]

current code:

#Check Col

for i in range(0, len(bo)):

if bo[i][pos[1]] == num and pos[1] != i:
   return False

should be:

#Check Col

for i in range(0, len(bo)):

if bo[i][pos[1]] == num and pos[0] != i:
   return False
