I get two dfferent error messages:
1) Traceback (most recent call last):
File "python", line 32, in
IndexError: list assignment index out of range
2) It looks like your game does not print "You missed my battleship!" when the guess is wrong.
I don't understand where i went wrong
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) - 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_row == ship_row and guess_col == ship_col: print "Congratulations!
