so in lines 129 to 135 i create a 2d array. But in lines 140, 141 i try to find the index of a specific character in the 2d arrray and the problem that keeps occuring is that list.index(x) x doesnt exist in the array, but the problem is that it does and im worryed that it could be the fact that it is the 2d array. Any ideas on why this is occuring or how to fix it?
Thanks
