# Row 1 col 1 is not the correct row/col

#1

Here's the output:

``````Guess Row: 1
Guess Col: 1
You missed my battleship!
O O O O O
O X O O O
O O O O O
O O O O O
O O O O O``````

What am I doing wrong? I've done EVERYTHING as told in the challenge.

``````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:"))

# Write your code below!
if guess_row not in range(5) or \
guess_col not in range(5):
print "Oops, that's not even in the ocean."
else:
if guess_row == ship_row and guess_col == guess_col:
print "Congratulations! You sank my battleship!"
elif board[guess_row][guess_col] == "X":
print "You guessed that one already."
else:
print "You missed my battleship!"
board[guess_row][guess_col] = "X"
print_board(board)``````

exercise 14? Your code seems fine indeed. What does the error message say? Try a different browser, it might be your browser is sending cached data

#3

There is no error message, my problem is that when I guess row 1 col 1, it's actually row 2 col 2 as you can see from the output above =(

#4

that is because arrays are zero indexed based? (counting starts from zero), so that would be 0,0.

You can of course change this, but that is far more difficult.

#5

Alright thank you now I understand. I just assumed from the PoV of a player row 1 col 1 should be the actual row 1 col 1.

#6

you could try to achieve this, but it is more difficult. I understand the logic from players PoV, but coding that is more difficult
