Problems generating Player sprite image with pygame

Question

I am trying to run the following pytho pygame code from this tutorial https://opensource.com/article/17/12/game-python-add-a-player. After correcting the indentation as I posted on this question 'Player' object has no attribute 'rect I tried to run the python code below followed by the file tree in the local folder called images as shown below. But I can't see hero.png in the game. I try also Pygame player sprite not appearing .

folder images:

stage.png: https://i.sstatic.net/Tmyok.jpg hero.png: https://opengameart.org/sites/default/files/spellun-sprite.png

My code:

import pygame  # load pygame keywords
import sys     # let  python use your file system
import os      # help python identify your OS

'''
Create class for player
'''

class Player(pygame.sprite.Sprite):
    def __init__(self):
      pygame.sprite.Sprite.__init__(self)
      self.images = []
      img = pygame.image.load(os.path.join('images','hero.png')).convert()
      self.images.append(img)
      self.image = self.images[0]
      self.rect.x = 40
      self.rect.y = 30
#cria a classe para o player

You have to add the attribute .rect to Player:

class Player(pygame.sprite.Sprite):
    def __init__(self):
      pygame.sprite.Sprite.__init__(self)
      self.images = []
      img = pygame.image.load(os.path.join('images','hero.png')).convert()
      self.images.append(img)
      self.image = self.images[0]
      self.rect = self.image.get_rect() # <----
      self.rect.x = 40
      self.rect.y = 30

Create an instance of Player. Create a pygame.sprite.Group and add palyer:

player = Player()
all_sprites = pygame.sprite.Group()
all_sprites.add(player)

Use draw() to draw all the Sprites in the Group. draw makes use of the image and rect attributes of the Sprites, to draw all the Sprites in the Group:

all_sprites.draw(world)

Respect the Indentation:

while main == True:

    # handle events
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit(); sys.exit()
            main = False

        if event.type == pygame.KEYDOWN:
            if event.key == ord('q'):
                pygame.quit()
                sys.exit()
                main = False

    # draw background
    world.blit(backdrop, backdropbox)

    # draw scene
    all_sprites.draw(world)

    # update display
    pygame.display.flip()
    clock.tick(fps)
