Enemys Wont Move Left And Right How Do I Fix This?

问题

I made my enemy class and underneath it I made a funtion that lets my enemy move left and right but for some reason it blits more then 1 enemy and stay at one position VIDEO

# enemys class
class enemy:
    def __init__(self,x,y,height,width,color):
        self.x = x
        self.y =y
        self.esright = [pygame.image.load("esright1.png"),
        pygame.image.load("esright1.png"),
        pygame.image.load("esright2.png"),
        pygame.image.load("esright3.png"),
        pygame.image.load("esright4.png"),
        pygame.image.load("esright5.png"),
        pygame.image.load("esright6.png"),
        pygame.image.load("esright7.png"),
        pygame.image.load("esright8.png"),
        pygame.image.load("esright9.png"),
        pygame.image.load("esright10.png"),
        pygame.image.load("esright11.png"),
        pygame.image.load("esright12.png"),
        pygame.image.load("esright13.png"),
        pygame.image.load("esright14.png"),
        pygame.image.load("esright15.png"),
        pygame.image.load("esright16.png"),
        pygame.image.load("esright17.png"),
                          ]
        self.esleft = [pygame.image.load("esleft1.png"),
        pygame.image.load("esleft1.png"),
        pygame.image.load("esleft2.png"),
        pygame.image.load("esleft3.png"),
        pygame.image.load("esleft4.png"),
        pygame.image.load("esleft5.png"),
        pygame.image.load("esleft6.png"),
        pygame.image.load("esleft7.png"),
        pygame.image.load("esleft8.png"),

        pygame.image.load("esleft14.png"),
        pygame.image.load("esleft15.png"),
        pygame.image.load("esleft16.png"),
        pygame.image.load("esleft17.png"),
                          ]
        self.esright = [pygame.transform.scale(image,(image.get_width()//3,image.get_height()//3)) for image in self.esright]
        self.esleft = [pygame.transform.scale(image,(image.get_width()//3,image.get_height()//3)) for image in self.esleft]
        self.height = height
        self.width = width
        self.vel = 5
        self.color = color
        self.anim_index = 0

        self.rect = pygame.Rect(x,y,height,width)

   def draw(self):
       self.rect.topleft = (self.x,self.y)
       window.blit(self.esright[self.anim_index], self.rect)
       self.anim_index += 1
       if self.anim_index == len(self.esright):
           self.anim_index = 0
           if self.x < 250:
               self.image_list.x -= self.vel
       else:
           window.blit(self.esleft[self.anim_index], self.rect)
           if self.anim_index == len(self.esleft):
               self.anim_index = 0
               if self.y > 350:
                   self.image_list.y += self.vel
