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
