How to create bullets in pygame?

I know that this was a few topics, but I still can’t figure out how to make my ship a bullet shot. I want to add to my bullets MOUSEBUTTONDOWN, shooting from the ship, as a sound effect. thanks for the help!

import sys, pygame, pygame.mixer
from pygame.locals import *

pygame.init()

size = width, height = 800, 600
screen = pygame.display.set_mode(size)

clock = pygame.time.Clock()

background = pygame.image.load("bg.png")
ship = pygame.image.load("ship.png")
ship = pygame.transform.scale(ship,(64,64))

shot = pygame.mixer.Sound("shot.wav")
soundin = pygame.mixer.Sound("sound.wav")

soundin.play()

while 1:
  for event in pygame.event.get():
    if event.type == pygame.QUIT:
      sys.exit()

    elif event.type == MOUSEBUTTONDOWN:
      shot.play()

  clock.tick(60)

  mx,my = pygame.mouse.get_pos()

  screen.blit(background,(0,0))
  screen.blit(ship,(mx-32,500))
  pygame.display.flip()

To do this, you need to go through several steps. You will need an image of a bullet, a way to save the location of bullets, a way to create bullets, a way to visualize bullets and a way to update bullets. You seem to already know how to import images, so I will skip this part.

. . bullets=[].

, . bullets.append([event.pos[0]-32, 500]) shot.play() .

, for . screen.blit(background, (0, 0)) :

for bullet in bullets:
  screen.blit(bulletpicture, pygame.Rect(bullet[0], bullet[1], 0, 0)

, - , :

for b in range(len(bullets)):
  bullets[b][0]-=10

, , . for, :

for bullet in bullets:
  if bullet[0]<0:
    bullets.remove(bullet)

, :

import sys, pygame, pygame.mixer
from pygame.locals import *

pygame.init()

size = width, height = 800, 600
screen = pygame.display.set_mode(size)

clock = pygame.time.Clock()

bullets=[]

background = pygame.image.load("bg.png")
ship = pygame.image.load("ship.png")
ship = pygame.transform.scale(ship,(64,64))
bulletpicture = pygame.image.load("You know what to do")

shot = pygame.mixer.Sound("shot.wav")
soundin = pygame.mixer.Sound("sound.wav")

soundin.play()

while 1:
  for event in pygame.event.get():
    if event.type == pygame.QUIT:
      sys.exit()

    elif event.type == MOUSEBUTTONDOWN:
      shot.play()
      bullets.append([event.pos[0]-32, 500])

  clock.tick(60)

  mx,my = pygame.mouse.get_pos()

  for b in range(len(bullets)):
    bullets[b][0]-=10

  for bullet in bullets:
    if bullet[0]<0:
      bullets.remove(bullet)

  screen.blit(background,(0,0))

  for bullet in bullets:
    screen.blit(bulletpicture, pygame.Rect(bullet[0], bullet[1], 0, 0)

  screen.blit(ship,(mx-32,500))
  pygame.display.flip()
