# Battleship 13/19 Help?

#1

I need help on this one. For some reason when i run this code it prints the X on one coordinate more than my input [Figure 1]. Also when i input a coordinate with either row or column number 5 it says it is out of the list index range [Figure 2]

[Figure 1]
In this example I inputed (2,2) and this was the result

[Figure 2}
Here i entered coordinates (5,5) and this was the results

``````  from random import randint

board = []

for x in range(0, 5):
board.append(["O"] * 5)

def print_board(board):
for row in board:
print " ".join(row)

print_board(board)

def random_row(board):
return randint(0, len(board) - 1)

def random_col(board):
return randint(0, len(board[0]) - 1)

ship_row = random_row(board)
ship_col = random_col(board)
guess_row = int(raw_input("Guess Row:"))
guess_col = int(raw_input("Guess Col:"))

print ship_row
print ship_col

if guess_row == ship_row and guess_col == ship_col:
print("Congratulations! You sank my battleship!")
else:
print("You missed my battleship!")
board[guess_row][guess_col] = "X"
print print_board(board)
if guess_row not in range(5) or guess_col not in range(5):
print("Oops, that's not even in the ocean.")
elif board[guess_row][guess_col] == "X":

else:
print("You missed my battleship!")
board[guess_row][guess_col] = "X"
print print_board(board)``````

To

``````guess_row = int(raw_input("Guess Row:") - 1)
guess_col = int(raw_input("Guess Col:") - 1)``````

Hi zeziba,

I have changed that but it still has an error and says:

``````O O O O O
O O O O O
O O O O O
O O O O O
O O O O O
Guess Row: 4
Traceback (most recent call last):
File "python", line 22, in <module>
TypeError: unsupported operand type(s) for -: 'unicode' and 'int'`indent preformatted text by 4 spaces```````
