what you place in the for loop should be indented:

``````a = [1,2,3]
for x in a:
print x``````

not the for loop itself

think what should be in the for loop (thus require additional indention)

#6

i cannot really understand you know i have been on thsis exercise for almost 2 hours please can you be more specific on how you want me to go about it please

#7

here:

``````    for turn in range(4):
# Everything from here on should go in your for loop!
# Be sure to indent four spaces!
guess_row = int(raw_input("Guess Row:"))
guess_col = int(raw_input("Guess Col:"))``````

everything from here on should go in the loop, what you place in the loop should be indented with 4 additional spaces:

``````for turn in range(4):
guess_row = int(raw_input("Guess Row:"))
guess_col = int(raw_input("Guess Col:"))``````

now, you can indent the rest of the script.

#8

This is it i did it as you said but i still could not get it ...from random import randint

``````board = []

for x in range(5):
board.append(["O"] * 5)

def print_board(board):
for row in board:
print " ".join(row)

print "Let's play Battleship!"
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)
print ship_row
print ship_col

for turn in range(4):
# Everything from here on should go in your for loop!
# Be sure to indent four spaces!
guess_row = int(raw_input("Guess Row:"))
guess_col = int(raw_input("Guess Col:"))

if guess_row == ship_row and guess_col == ship_col:
print "Congratulations! You sunk my battleship!"
else:
if (guess_row < 0 or guess_row > 4) or (guess_col < 0 or guess_col > 4):
print "Oops, that's not even in the ocean."
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"
if turn == 3:
print "Game Over"
# Print (turn + 1) here!
print "Turn", turn +1
print_board(board)``````

#9

here:

``````else:
if (guess_row < 0 or guess_row > 4) or (guess_col < 0 or guess_col > 4):``````

after else there should also be additional indention. You do know how indention works in python and when to use it for nesting things inside a function/for loop/if/else and so on?

#10

i still cannot get it dear i am badly stock here

#11

i do not know if there is another way you could do this?

#12

Also include the error message

#13

it says
Oops, try again.
Your code looks a bit off. Check the Hint if you need help! Your
code threw the following error: invalid syntax (python, line 39)

#14

#15

yes i just read it but still cannot figure out to go about

#16

#17

we are nearly there, showing the answer would violate the guideines

this lines:

``````else:
print "You missed my battleship!"
board[guess_row][guess_col] = "X"``````

else should be after the elif you guessed that one already.

#18

ok so you mean i should indent this lines like that?

#19

no, you have to think how the line should be indented, walk through the logic of the game
