Including save option in my battleship game



The user should be able to save the game (using files) and come back to it at any time.

I'm not sure how to take my battleship game and include a save option after each move so that if the game is left it can be called again

It would be lovely if someone could write into my code coding on how to do that and name the file whatever and I can save that onto my desktop and call it and store the saved info into it. I'm terrible at just understanding words that's why I need code. Please help!!!

Replace this line with your code. 
#def save();
#what it does , write entire board

#def load():
#call load function at beginning
#board[r][c] == "x"
from random import randint
# Define blank list
board = []
board1 = []
#Generate rows with length of 3
for row in range(10):
  # Appen a blank list to each row cell
  for column in range(10):
    # Assign x to each row
    #board[row].append(str(row) + "," + str(column))

# Function will print board like an actual board
def print_board(board):
    print("  A B C D E F G H I J")
    for row in range(len(board)):
        print(str(row+1)+ " " + " ".join(board[row]))


#board[4][4] = 'x' # row,column  board[row][column]
alpha = ["A", "B", "C", "D", "E", "F", "G", "H", "I", "J"]
for i in range (0,5):
    c = input('where do you want your column? pick (A-J)')
    r = int(input('where do you want your row? pick (1-10)'))
    f = alpha.index(c)
    board[r-1][f] = "X"

for i in range(0,5):
    c = randint(0,9)
    r = randint(0,9)
    board1[r][c] = "X"

b = any("X" in sublist for sublist in board)
b1 = any("X" in sublist for sublist in board1)

while( b == True and b1 == True):
    print("user turn")
    d = input("what column do you want to hit?")
    e = int(input("what row do you want to hit?"))
    i = alpha.index(d)

    if board1[e-1][i] == "X":
        board1[e-1][i] = "O"
    print("computer turn")
    d = randint(0,9)
    e = randint(0,9)

    if board[e][d] == "X":
        board[e][d] = "O"

    b = any("X" in sublist for sublist in board)
    b1 = any("X" in sublist for sublist in board1)

if b1 == True:
    print("you lost")
if b == True:
    print("you won")


I know how to do it, but I'm not going to write into your code. My reason is that I don't believe that's how people learn - they learn by writing things out themselves and researching how to do things.

I will tell you this: file I/O will be very helpful to you here. If you're going for a basic system, look into the open() object and use it with a .txt file like data.txt. It's used for opening, closinig, reading and writing to files.

If you want something a little more advanced after that, research something called CSV. It uses the open() object, but the file would be data.csv and it's a little more complex (but SO much better for data storage than a plain text file). It's good for storing specific values.

However, in this case, it would probably be easier to use a mixture of the two. I would store the board in a plain text file and any specific values (such as amount of attempts, who's turn it is (in a two player game)).

Hope this helps!
