I need some random image spawn in my game but i just don't know now

Question

I'm trying to do a scroller type game but I need help with the coins spawning.

This is my code:

import os
import pygame


WIDTH, HEIGHT = 900, 500
WIN = pygame.display.set_mode(((0, 0)), pygame.FULLSCREEN)
pygame.display.set_caption('First game')
image = pygame.image.load('Game_icon.png')
pygame.display.set_icon(image)

GREEN = (0, 150, 0)
WHITE = (255, 255, 255)
BLACK = (0, 0, 0,)
FPS = 60
FPS_SLOMO = 30
VEL = 5
PLAYER_WIDTH, PLAYER_HEIGHT = 55, 55
COIN_WIDTH, COIN_HEIGHT = 20, 20

PLAYER_IMAGE = pygame.image.load(os.path.join('Assets', 'Player.png'))
PLAYER = pygame.transform.rotate(pygame.transform.scale(
    PLAYER_IMAGE, (PLAYER_WIDTH, PLAYER_HEIGHT)), 0)

COIN_IMAGE = pygame.image.load(os.path.join("Assets", 'coin.png'))
COIN = pygame.transform.rotate(pygame.transform.scale(
    COIN_IMAGE, (COIN_WIDTH, COIN_HEIGHT)), 0)

def draw_window(player, coin):
    WIN.fill(GREEN)
    WIN.blit(PLAYER, (player.x, player.y))
    WIN.blit(COIN, (coin.x, coin.y))
    pygame.display.update()


def main():
    player = pygame.Rect(100, 300, PLAYER_WIDTH, PLAYER_HEIGHT)
    coin = pygame.Rect(100, 100, COIN_WIDTH, COIN_HEIGHT)
    clock = pygame.time.Clock()
    run = True
    while run:
        clock.tick(FPS)
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                run = False

        keys_pressed = pygame.key.get_pressed()
        if keys_pressed[pygame.K_a]:
            player.x -= VEL
        if keys_pressed[pygame.K_d]:
            player.x += VEL
        if keys_pressed[pygame.K_w]:
            player.y -= VEL
        if keys_pressed[pygame.K_s]:
            player.y += VEL
        if keys_pressed[pygame.K_LSHIFT]:
            clock.tick(FPS_SLOMO)
        draw_window(player, coin)

    pygame.quit()


if __name__ == "__main__":
    main()

Answer 1

If I understand your problem well, it could be solved like this:

import random

NUM_COINS = 100

coins = [[
random.randint(0, WIDTH), random.randint(0, HEIGHT)] for _ in range(NUM_COINS)]

def draw_window(player):
    WIN.fill(GREEN)
    WIN.blit(PLAYER, (player.x, player.y))
    for pos in coins:
        WIN.blit(COIN, (pos[0], pos[1]))
    pygame.display.update()

I hope it will help you, Adam.

PS: I would recommend reducing the VEL and increasing the FPS for a better game experience

Una manera de cargar imagenes aleatoriomente seria recurriendo al modul os por ejemplo:

def extraer_imagenes(ruta_imagenes):
    listado_de_img  = os.listdir("ruta_imagenes") #Listara todos los nombres de las imagenes        
    img_aleatoria = random.choice(listado_de_img)
    return img_aleatoria

De esta manera obtendras una ruta aleatoria de las imagenes que quieres que se carguen
