Oops, try again. Make sure your prompts are exactly as written in the instuctions. No changing the capitalization or using extra spaces!
I would have expected that it does not matter wether I type "Guess row: " or "Guess Row: ", but it does.
Row (and Col) need to be capitalized and then it works, but I do not understand why they need to be capitalized?
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) 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) # Add your code below! guess_row = int(raw_input("Guess row: ")) guess_col = int(raw_input("Guess Col: "))
