Switch your else and elif: You're checking in your elif if it's true or not. So you don't assign it "=" you check it "==" . Then it passes on to else if it's not equal to and assigns it to "X".

``````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"``````

Thanks, it helped!
Btw, you have a typo
"elif (board[guess_row][guess_col] == "X":)" --> "== "X"):"
