# Not Again!

#1

The code I have written for the entire battleship exercise is below. The elif statement at the bottom of the code is giving me some trouble, and I don't know how to fix it. I thought that I had written it correctly, but every time I click Save and Submit code, I get an invalid syntax error pointing to line 42, the elif line. I checked the forums, and I seem to have written it the same way everybody else has, but mine just won't work. Please help!

``````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_col == ship_col and guess_row == ship_row:
print "Congratulations! You sank my battleship!"
else:
print "You missed my battleship!"
board[guess_row][guess_col] = "X"
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."
else:
print "You missed my battleship!"
board[guess_row][guess_col] = "X"
print_board(board)
elif(board[guess_col][guess_row]=="X"):
print "You guessed that one already."``````

the order of operations should be:

check if users guess is in ocean (if)
check if user guessed this coordinates already (elif)
user missed battle ship (else)

don't update board/print you missed before you validate guess is on board and not guessed already
