Bullet to Enemy Collision Detection - python-3.x

Question

After a few hours of looking for code to reference. I failed i tried to re-write the collision code but it failed. Now my Question is
How can i fix my code to make it delete the Enemy ship when the bullet hits him
Note: Im not asking for you to do it, i just need it further explained what the problem or where im making a mistake
The Code Segment
for bullet in Bullets:
Hit_list = pygame.sprite.Group()
if pygame.sprite.collide_rect(bullet, Enemy_list):
Hit_list.add(hit)
for hit in Hit_list:
Bullets.remove(bullet)
All.remove(bullet)
All.remove(hit)
Enemy_list.remove(hit)
# If the bullet goes off the screen it deletes
if bullet.rect.y < 0:
Bullets.remove(bullet)
All.remove(bullet)
The Error
Traceback (most recent call last):

if pygame.sprite.collide_rect(bullet, Enemy_list):

Answer 1

Your If condition uses collide_rect:
pygame.sprite.collide_rect()
Collision detection between two sprites, using rects.
collide_rect(left, right) -> bool
You pass 2 parameters - a Bullet, and a SpriteGroup. The error is telling you that a SpriteGroup does not have a Rect attribute.
I think you wanted to use:
pygame.sprite.spritecollide()
Find sprites in a group that intersect another sprite.
spritecollide(sprite, group, dokill, collided = None) -> Sprite_list
Apart from this, I would change all the variable names to lowercase. I have also noticed that your if bullet.rect.y < 0: is under the collide test. I think you want to remove a Bullet from the screen even if there is no collision.
