python - Pygame Sprite. How to create different enemies/images from same class? -

i building tiny platform based game pygame. want go having 1 graphic enemies, several different graphics. idea put them in array , draw randomly upon initing several sprites randomly picked graphics.

but result either enemy1.png or enemy2.png sprites. not sure if simple , not able see it, or if need extend enemy class each new graphic want enemies have?

i tried 2 things same, , same result both.

first idea:

class enemy(pygame.sprite.sprite):      enemyarray = [pygame.image.load('enemy1.png'), pygame.image.load('enemy2.png')]      def __init__(self, location, *groups):         super(enemy, self).__init__(*groups)          in self.enemyarray:             self.image = choice(self.enemyarray)          self.rect = pygame.rect.rect(location, self.image.get_size())         self.direction = 1 

second idea:

class enemy(pygame.sprite.sprite):      enemyarray = [pygame.image.load('enemy.png'), pygame.image.load('bomb.png')]     in enemyarray:         image = choice(enemyarray)      def __init__(self, location, *groups):         super(enemy, self).__init__(*groups)          self.rect = pygame.rect.rect(location, self.image.get_size())         self.direction = 1 

i've used internet find guidance, can't find seems handle issue. helpful, ready made code snippets links might enlighten me.

update:

class game(object):     def main(self, screen):         ...         self.enemies = tmx.spritelayer()         enemy in self.tilemap.layers['triggers'].find('enemy'):             enemy((enemy.px, enemy.py), self.enemies)         self.tilemap.layers.append(self.enemies) 

i use tilemap i've created in tiled, each enemy-trigger, there enemy spawning. enough?

in second idea have line:

image = choice(enemyarray) 

this should not work because making local variable image, not stored enemy class @ all. don't have error in first idea. correct way set attribute this:

self.image = choice(enemyarray) 

then can change:

 in enemyarray:      image = choice(enemyarray) 

into:

image = choice(enemyarray) 

because should make no difference, throwing dice 2 times when have 2 pictures in enemyarray.
