AttributeError: 'Sprite' object has no attribute 'rect'

Question

Hi I've got a problem with Sprite class. I defined self.image and self.rect in my class init function and still getting an error: AttributeError: 'Sprite' object has no attribute 'rect'

I've read couple of topics related to this problem and always somebody was missing these attribiutes. I have no clue how to resolve this problem. In line

player.draw(screen)

I am getting an error: AttributeError: 'Player' object has no attribute 'image'

import pygame


class Player(pygame.sprite.Sprite):
    def __int__(self):
        pygame.sprite.Sprite.__init__(self)
        self.image = pygame.image.load('graphics/player/p1_walk01.png')
        self.rect = self.image.get_rect(midbottom=(200, 330))


pygame.init()
screen = pygame.display.set_mode((800, 400))
pygame.display.set_caption('Game')
clock = pygame.time.Clock()

# Backgrounds
sky_surf = pygame.image.load('graphics/background/bg.png').convert()
ground_surf = pygame.image.load('graphics/background/ground.png').convert()

player_obj = Player()
player = pygame.sprite.GroupSingle()
player.add(player_obj)

while True:
    screen.blit(sky_surf, (0, 0))
    screen.blit(ground_surf, (0, 330))
    player.draw(screen)

pygame.display.update()
clock.tick(60)
