Converting Range Values to Integers

I'm developing a game in pygame where enemy ships will begin off screen then move vertically on the Y-axis towards the player.

However, I'm having a bit of trouble accessing the location of the enemy since it's all relative to a range. I'm not exactly too sure of how to explain it, but here's what I have for the Enemy Class:

class EnemyActive(pygame.sprite.Sprite):
    def __init__(self):
        super().__init__()
        enemy_img_list = ['enemyshipone.png', 'enemyshiptwo.png',
                      'enemyshipthree.png','enemyshipfour.png']
        enemy_img = random.choice(enemy_img_list)
        self.image = pygame.image.load(enemy_img)
        self.rect = self.image.get_rect()
        self.rect.x = random.randrange(0,400)
        self.rect.y = random.randrange(-200,-10)
        self.speed = random.randrange(1,3)

    def update(self):
        self.rect.y += self.speed

    def getCoord(self):
        return (self.rect.x, self.rect.y)

So, when I try to access the position using another function, which takes in an (x,y) coordinate:

particle_list = particles.create_particles(particle_list,enemy.getCoord())

It comes back with an error stating:

numbers = range(-5, -1) + range(1, 5)

TypeError: unsupported operand type(s) for +: 'range' and 'range'

I'm not going to lie and say that I fully understand the error, but I do see logic behind the reasoning for it. How can I actually get my 'getCoord' function to send the appropriate coordinates?
