Why do I have to close pygame window again and again?

Question

I made a car game and here is my code:-

import pygame
import random
from pathlib import Path
import os
os.chdir(Path(__file__).parent)

win_w = 300
win_h = 480
pygame.init()
win = pygame.display.set_mode((win_w, win_h))
#icon = pygame.image.load('icon.png')
#pygame.display.set_icon(icon)
pygame.display.set_caption('Game')

def main():
    blue = (51, 51, 255)
    grey = (128, 128, 128)
    light_grey = (200, 200, 200)
    orange = (255, 175, 26)
    white = (255, 255, 255)
    black = (0, 0, 0)
    green = (0, 255, 0)
    red = (255, 71, 26)
    car_speed = 15
    score = 0
    time = 85
    
    class mainCar(pygame.sprite.Sprite):

            win.blit(self.image, (self.rect.x, self.rect.y))

pygame.quit

Now when ever I lose, I press spacebar to start again. For eg. I did 4 tries and now I m tired. So I want to quit the game. As I tried 4 times I will have to click X 4 times!

I want to close it all in 1 time only...

Now when I click close button in window then it pops up again and again till how much times I retried. If I retried 3 times then I have to close window 3 time, why?

I just want it to close only in 1st time... I hope you are understanding my words!

Please help me that when I close window 1 time everything closes If you don't understand my thing than you may try the code and retry 2 - 3 times and see...

THANK YOU!!!

You're calling main recursively. In fact, you are not restarting the game, but you are starting a completely new game within the game. When you want to quit, you have to close all the games you've started. Write a function or method that resets all game-related variables. Call this function instead of main.
