string index out of range

[cusick11]

Okay so I'm having trouble finding my problem I know the line of code that Idle is telling me that needs corrected is not the problem, but I can't seem to find what the problem is. Please let me know if you can find it or if I need to post more of my code. Thanks

The Error:

Error:
  File "/home/ryan/Desktop/CS3560/Homework_3/prog3_new.py", line 352, in print_board
    line = line + board[row][col] + "  |  "
IndexError: string index out of range

The code:

def print_board(board, count):
    line = ""
    if(count > 0):
        for row in range(0, 4):
            for col in range(0, 4):
                if(col == 0):
                    line = line + "  "

                if(col == 3 and row != 3):
                    line = line + board[row][col]+ "  \n------------------------\n"
                elif(col == 3):
                    line = line + board[row][col]+ "  "
                else: line = line + board[row][col] + "  |  "
                
        print line
    else:
        for row in range(0, 4):
            for col in range(0, 4):
                if(col == 0):
                    line = line + "  "
                    
                if(col == 3 and row != 3):
                    line = line + board[row][col]+ "  \n------------------------\n"
                elif(col == 3):
                    line = line + board[row][col]+ "  "
                else:
                    line = line + board[row][col] + "  |  "
            
        return line
