I'm making a game with pygame, Space Invaders, and now I'm doing the collisions between the shoot of the eneimies and the player (those are images), but it doesn't work all time and I'd like to know why, and what's the solution. Thanks for attention! Here's the code:

Here is a collision detection code that will sense if one rectangle collides with another rectangle, if the enemy's shot hits the player:
if player x < shot x + player width and player x + shot width > shot x and player y < shot y + player height and shot height + player_y > shot y:
It works by sensing if any of the edges of the bullet are touching any edges of the character. I hope this helps.
