INSTRUCTIONS:
Add an elif to see if the guessed location already has an 'X' in it.
If it has, print "You guessed that one already."

PROBLEM:

#2

the structure of your code is a bit off, look at the pseudo code below:

``````if guessed ship:
print "guessed ship"
else:
# this else clause will handle miss, first check if guess is on board
if not in range:
print "not on board"
print "you guessed that one already"
else:
print "you missed"
# update board``````

#3

oouh ok i fixed that but i canÂ´t write the guessed already that itÂ´s required for the code

#4

why not?

#5

it doesnÂ´t run

#6

how would you write that?

#7

can i see an updated version of your code?

#8

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

print ship_row
print ship_col

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

print print_board(board)``````

#9

this line:

``board[guess_row][guess_col]="X"``

will update the coordinate with `X`, but why do you place it so early in your code? It should be here:

``````          print "You missed my battleship!"
# update board here, don't print X
print "X"``````

`board[guess_row][guess_col]` will retrieve the coordinate the user guessed, so we could also use that for `elif` condition to see if the coordinate the user guessed equals `"X"`

got it, thanks!!!!!!!
