Python -- 3 dices game question by using while loop

I am a new learner on Python, I created a game to roll 3 dices randomly. I want to know how to go back to the "play" under "else". Please check my screenshot
import random
game = False
game1 = False
def roll():
money = 0
while game == False :
money += 1
key = input("Please hit 'y' to roll the 3 dicks: ")
if key == "y":
roll1 = random.randint(0,10)
roll2 = random.randint(0,10)
roll3 = random.randint(0,10)
print("Roll 1,2,3 are: ", roll1, roll2, roll3)
else:
print("Invalid input, try again")
return roll()
if roll1 == roll2 == roll3:
money +=1
print("You Win!")
print("Your award is ", money)
game == False
else:
play = input("Loss, try again? y or n? ")
if play == "y":
money -= 1
game == False
elif play == "n":
break
else:
??????????????????????
roll()

You can just put it inside a while loop there:
else:
while True: # you can
play = input("Loss, try again? y or n? ")
if play == "y":
money -= 1
game == False
elif play == "n":
break
else:
pass

How log my score best out of three and use different symbols for the players? Python

I'm making a 2-play Battleship game in python and have been struggling with this for a while now:
I apologise if the question is poorly worded but I was to know how I can make my game log the match score at the end of the three games with something like:
print('Match score is' + score + 'Player' + (whoever) + 'wins!)
I'm not entirely sure how to implement this myself I have a range for games in range(3), but I don't know how to log the final score.
Also, how can I change the symbol for player_two so that I am not using an 'X' for both players? I've tried changing the input_check() but I get more errors than I did before.
from random import randint
game_board = []
player_one = {

You can use style string formatting to print the log.
print('Match score is %d : %d(Player1 : Player2)' % (player_one["wins"], player_two["wins"]))
For more information about string formatting, check this link.
To change the symbol for Player 2, you can change the following code.
elif board[guess_row][guess_col] == "X" or board[guess_row][guess_col] == "Y":
print("You guessed that one already.")
else:
print("You missed my battleship!")
if player == player_one:
board[guess_row][guess_col] = "X"
else:
board[guess_row][guess_col] = "Y"

Python Battleships Game

I am currently making a simple Battleships game using Python 3, but I can't seem to get the board to display. Here is my code;
# Battleships
def main():
pass
if __name__ == '__main__':
main()
from random import randint
# this initialises the board
board = []
for x in range(5):
board.append(["O"] * 5)
def print_board(board):
for row in board:
print (" ".join(row))
# this starts the game and prints the board
print ("Let's play Battleship!")
print_board(board)
# defines the location of the ship
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)
# asks the player to make a guess
for turn in range(5):
guess_row = int(input("Guess Row:"))
guess_col = int(input("Guess Col:"))
# if the player guesses correctly, then the game ends cleanly
if guess_row == ship_row and guess_col == ship_col:
print ("Congratulations! You sunk my battleship!")
else:
# if the player guesses outside the board, then the following message appears
if (guess_row < 0 or guess_row > 4) or (guess_col < 0 or guess_col > 4):
print ("Oh dear, you've hit an island!")
# a warning if the guess has already been made by the player
elif(board[guess_row][guess_col] == "X"):
print ("That guess has already been made.")
# if the guess is wrong, then the relevant board place is marked with an X
else:
print ("You've missed my battleship!")
board[guess_row][guess_col] = "X"
# prints the turn and updates the board accordingly
print ("Turn " + str(turn+1) + " out of 5.")
print_board(board)
# if the user has had 5 guesses, it's game over
if turn >= 3:
print ("You sunk my battleship! We're gonna need a bigger boat.")
The game accepts the co-ordinates, but doesn't print anything to do with the board or if the player makes a repeated guess or one that's outside the field of play.
Any help would be much appreciated!

Your code asks for 5 sets of guesses before it does anything with them, because the code to respond to a guess is outside of the loop asking for the guesses. I'm, ahem, guessing that in your testing you never entered enough guesses to get past that loop. Move the guess-processing code into the loop, and you should at least see reactions to those guesses.

You are iterating over the loop THEN all the if statements. Put all the if statements inside the for loop. Add a counter saying if you hit my ship add one point (score += 1) then
if score >= 3:
print ("You sunk my battleship! We're gonna need a bigger boat.")

Beginner Python-Looping to the beginning of a programme

I will start fresh! I have included the full code so you can get a picture for what i am trying to do. Prob (1) I can not loop back to the very beginning. Prob (2) It is not looping # the While higher_or_lower part of the code. it just goes through the if and else higher_or_lower statements. Thanks

Ok, a primer in how Python indentation works.
number = 1
while number < 10:
print(number)
number += 1
print("this will print everytime because it's inside the while")
Output:
1
this will print everytime because it's inside the while
2
this will print everytime because it's inside the while
3
this will print everytime because it's inside the while
4
this will print everytime because it's inside the while
5
this will print everytime because it's inside the while
6
this will print everytime because it's inside the while
7
this will print everytime because it's inside the while
8
this will print everytime because it's inside the while
9
this will print everytime because it's inside the while
Notice that the second print prints every time because of it's indentation.
Now the second example:
number = 1
while number < 10:
print(number)
number += 1
print("this will print AFTER the loop ends")
Output:
1
2
3
4
5
6
7
8
9
this will print AFTER the loop ends
See how it only printed after the loop ended? That is because of the indentation. You should correct your code and indent it properly...
Ok, I corrected the code and it seems to be working now. Most of it was because of the indentation. Please try to understand how it works...

It looks like adding a little structure would help you out.
Something like this might help you with doing your control flow. Hopefully gives you an outline that makes sense and makes it easier to run the loop multiple times.

The purpose here of using this loop is in a game, dice are rolled, and you are rewarded money per the number of your roll, unless you roll a roll matching your first roll. Now, I need the loop to stop if that occurs, and I know this is easily achievable using a break statement, however, I have been instructed no break statements are allowed. How else can I get the loop to terminate if roll == first_roll?

You can:
Use a flag variable; you are already using one, just reuse it here:
running = True
while running:
# ...
if roll == first_roll:
running = False
else:
# ...
if answer.lower() in ('n', 'no'):
running = False
# ...
Return from a function:
def game():
while True:
# ...
if roll == first_roll:
return
# ...
if answer.lower() in ('n', 'no'):
return
# ...
Raise an exception:
class GameExit(Exception):
pass
try:
while True:
# ...
if roll == first_roll:
raise GameExit()
# ...
if answer.lower() in ('n', 'no'):
raise GameExit()
# ...
except GameExit:
# exited the loop
pass

You could use a variable that you will set to false if you want to exit the loop.
cont = True
while cont:
roll = ...
if roll == first_roll:
cont = False
else:
answer = input(...)
cont = (answer == 'Y')

Get some bonus points and attention, use a generator function.
from random import randint
def get_a_roll():
return randint(1, 13)
def roll_generator(previous_roll, current_roll):
if previous_roll == current_roll:
yield False
yield True
previous_roll = None
current_roll = get_a_roll()
while next(roll_generator(previous_roll, current_roll)):
previous_roll = current_roll
current_roll = get_a_roll()
print('Previous roll: ' + str(previous_roll))
print('Current roll: ' + str(current_roll))
print('Finished')

Is continue allowed? It's probably too similar to break (both are a type of controlled goto, where continue returns to the top of the loop instead of exiting it), but here's a way to use it:
while answer == 'Y':
roll = get_a_roll()
display_die(roll)
if roll == first_roll:
print("You lost!")
answer = 'N'
continue
...
If when you lose, answer is hard-coded to "N" so that when you return to the top to re-evaluate the condition, it is false and the loop terminates.
