# 16/19 Game Over

#1

Why is this code not working?

Here’s my code:

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

# 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”
# Print (turn + 1) here!
print_board(board)

for turn in range(4):
if “win”:
print “you win!”
break
else:
print “game over!”

for turn in range(4):
# Make a guess
# Test that guess
print “Turn”, turn + 1

Let’s play Battleship!
O O O O O
O O O O O
O O O O O
O O O O O
O O O O O
3
0
Guess Row: 1
Guess Col: 2
You missed my battleship!
O O O O O
O O X O O
O O O O O
O O O O O
O O O O O
you win!
Turn 1
Turn 2
Turn 3
Turn 4
None

Oops, try again. Did you add your if statement with the “Game Over” message?

#2

Format your code. They asked you to print game over after user misses 3 times

#3

I redone my code, and it worked, but WHY?

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

Everything from here on should go in your for loop!
Be sure to indent four spaces!

for turn in range(4):
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”
print “Turn”, turn+1
if turn == 3:
print “Game Over”
print_board(board)
