PyMine | A fast and easy to use , moddable , Python based Minecraft | Video Game library

Your Player class does not have a pygame rect object, which is required for the spritecollideany function. So passing self into this line:

return pygame.sprite.spritecollideany(self, enemies)

You are passing your own custom class Player to the function, you need to add a rect object to your class so pygame knows where it is.

So instead of using self.x self.y for player you should have a self.rect initialized at the start and use self.rect.x, self.rect.y for those variables. Making sure to update this rect as your player moves. This puts things in a format that pygame understands.
