'Prolog: show a list contained within a list
I currently have the following facts defined in a Prolog program:
hobbies([jarrod, [gaming, running, boxing]]).
hobbies([james, [programming, gaming, drawing]]).
What query could display a list of jarrod's hobbies? (i.e. [gaming, running, boxing])
Solution 1:[1]
@false is correct:
hobbies([jarrod, Hobbies]).
it unifies hobbies against all the facts, and then only gets the ones where the first element of the list is jarrod. Then it unifies Hobbies with the list of hobbies.
