I don't understand how it all works together, can someone explain to me please?

``````from random import randint
#Generate Map
board = []

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

def print_board(board):
for row in board:
print ":".join(row)
#Show Board
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)
#Generate Random Ship
ship_row = random_row(board)
ship_col = random_col(board)

# 4 Turns to Guess Where Ship Is
for turn in range(4):
print "Turn", turn + 1
guess_row = int(raw_input("Guess Row:"))
guess_col = int(raw_input("Guess Col:"))
# If Guess is Correct
if guess_row == ship_row and guess_col == ship_col:
print "Congratulations! You sunk my battleship!"
break
# If Guess isn't correct, check reasons.
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!
if turn == 3:
print "Game Over"
print_board(board)``````
