Prolog change from a list to a conjunction

suppose i have a list

[p(X,Y) , h(n,U) , f(U,R)]

i want to change to a conjunction and assign the conjunction to a variable the output should be : Output:

Variabile = p(X,Y) , h(n,U) , f(U,R)

you ha开发者_StackOverflow社区ve any idea?

You can only assign terms to variables. Conjunction of terms is not a valid term.

Maybe you want this:

list_to_conj([H], H) :- !.
list_to_conj([H | T], ','(H, Conj)) :-
    list_to_conj(T, Conj).

Usage examples:

?- list_to_conj([], Variable).
false.

?- list_to_conj([a], Variable).
Variable = a.

?- list_to_conj([a, b], Variable).
Variable = (a, b).

?- list_to_conj([p(X,Y) , h(n,U) , f(U,R)], Variable).
Variable = (p(X, Y), h(n, U), f(U, R)).

?- list_to_conj([writeln(hello), writeln(world)], Variable), call(Variable).
hello
world
Variable = (writeln(hello), writeln(world)).
