Infinite looping Issue Python. Can’t quit game

I made a code for Blackjack in Python and whenever I run blackjack_game(deck) saying no to the ‘Play Again’ input should quit the game but it doesn’t. Funds going zero and below should also trigger the game to quit but it doesn’t.

This is what it looks like:

import random
import os


 
# The Card class definition
class Card:
    def __init__(self, suit, value, card_value):
         
        # Suit of the Card like Spades and Clubs
        self.suit = suit
 
        # Representing Value of the Card like A for Ace, K for King
        self.value = value
 
        # Score Value for the Card like 10 for King
        self.card_value = card_value




# Clear the terminal
def clear():
    os.system("clear")

# Print player stats
def print_stats(player_name, funds, wins, losses, ties, blackjacks, busts):
    print('Player: ', player_name)
    print('Funds: $', funds)
    print(f'Wins: {wins} Losses: {losses} Ties: {ties} Blackjacks: {blackjacks} Busts: {busts}')

I added a quit() that should trigger should ‘while play_again == ‘Y’:’ no longer be true. This should have quit the game and stopped it from running. Instead it prompts the user again for a betting amount, acting as if I chose ‘Y’ instead.

I also tried removing:

play_again = 'Y'

and replacing this code block:

end_choice = input('Play again(Y/N)?: ')
play_again = end_choice.upper()

with this:

end_choice = input('Play again(Y/N)?: ')
if end_choice.upper() == 'N':
 exit()

But it still wouldn’t quit and stayed as an infinite loop. Help me please, I’ve been stuck with this issue all day.

Answer

Can you please try by replacing from this:

    # Bets
    while play_again == 'Y':
        while end_game == False:
            while funds > 0:
                while bet == 0:
                    bet = int(input('Enter bet amount: '))

                    if bet > funds:
                        print('Insufficient funds')
                        bet = 0

With

    # Bets
    while play_again == 'Y':
        while end_game == False:
            if play_again != 'Y':
                break
            while funds > 0:
                if play_again != 'Y' or end_game:
                    break
                while bet == 0:
                    bet = int(input('Enter bet amount: '))

                    if bet > funds:
                        print('Insufficient funds')
                        bet = 0

I believe we don’t even need to add end_game as it is unnecessary in current scope.

These are nested while loop and parent while loop will not break until child breaks. so we need to add extra condition in child while loop which break it on the basis of parent check.
