Test Run


whenever I enter a guess that is within in the range of the board the code works just fine, but as soon as I enter a guess that is outside of range(5) I get the following error:

Traceback (most recent call last):
File "python", line 31, in
IndexError: list index out of range

why doesn't it give me the "That's not even in the ocean"?

Replace this line with your code. 
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)


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

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


because here:

elif board[guess_row][guess_col] == "X":

you try to access the board before validating the shot is even in the ocean.

if the user already guessed a specific set of coordinates should be after you checked if the shot is in the ocean


that fixed it! thank you so much :smile:
