How can I check collisions between actors in pygame using "actor.collidepoint(pos)"

I'm very new to pygame and am trying to make a game where the actor try's to hit the gem, but I cant figure out how to use the "actor.collidepoint(pos)" function for that! Answers are greatly appreciated!

See Actor:

Actors have all the same attributes and methods as Rect, including methods like .colliderect() which can be used to test whether two actors have collided.

Supposing you have to Actor objects:

player = Actor("player_image.png")
gem    = Actor("gem_image.png")

Use colliderect method to detect the collision between the actors:

if player.colliderect(gem):
    print("hit")
