Is there a way to terminate my program after a condition is met? (If a player won the game)

Question

I am new to python. I am trying to recreate the snakes and ladders game. I am not able to terminate the program if a player won. After the player has won (reached 100 or any board size), my program still asks another player to roll a dice and my game just continues.

Here is the Player class I created. You can find a win condition in Player.turn().

class Player:

    def __init__(self, name):

        self.name = str(name)

        self.position = int()

    def ask_to_roll(self):

        while True:

            command = str(input("Press enter to roll the dice.\n> "))

            if command == "":

                break

            else:

                print("Invalid")

                continue

    def roll_dice(self):

        print(f'{self.name} is rolling the dice...')

        time.sleep(delay)

        roll_result = random.randint(1, dice_faces)

        print(f"It's a {roll_result}!")

        time.sleep(delay)

        return roll_result

    def check_for_snakes_ladders(self):

        if self.position in snakes.keys():

            print(random.choice(snake_bite))

            time.sleep(delay)

            print(f'{self.name} fell from {self.position} to {snakes[self.position]}')

            time.sleep(delay)

            self.position = snakes[self.position]

        elif self.position in ladders.keys():

            print(random.choice(ladder_jump))

            time.sleep(delay)

            print(f'{self.name} climbed from {self.position} to {ladders[self.position]}')

            time.sleep(delay)

            self.position = ladders[self.position]

        else:

            pass

    def turn(self):

        print(f"\nIt's {self.name}'s turn")

        self.ask_to_roll()

        roll_result = self.roll_dice()

        new_position = self.position + roll_result

        if new_position > board_size:

            print(f"Oops you need to get {board_size - self.position}")

            pass

        elif new_position == board_size:

            print(f'{self.name} won')*

        elif new_position < board_size:

            print(f'{self.name} moved from {self.position} to {new_position}')

            time.sleep(delay)

            self.position = new_position

            self.check_for_snakes_ladders()

Answer 1

Use the below code: 

elif new_position == board_size:

    print(f'{self.name} won')

    sys.exit(0)

Remember to import sys at the top of the file
