It should be possible to return arbitrary sequences and not just lists from external python functions.

Are generators supported ?

def g():
    yield from (1, 2, 3)

[rkaminsk]

Yes, anything that is iterable is supported. But note that str and tuple are converted to clingo.Symbol (of type clingo.SymbolType.String and clingo.SymbolType.Function).

Hi! I have a problem. I run this code with the clyngor in python
`from clyngor import ASP, solve

answers = ASP("""
rel(a,(c;d)). rel(b,(d;e)).
obj(X):- rel(X,) ; rel(X,Y): att(Y).
att(Y):- rel(,Y) ; rel(X,Y): obj(X).
:- not obj(X):obj(X).
:- not att(Y):att(Y).
""")
for answer in answers:
print(answer)and I get this error
FileNotFoundError: [WinError 2] The system cannot find the file specified
`

@marypopa Sounds like a clyngor related problem, doubled with an ASP syntax error. Please file this issue on clyngor repository, i will study it as soon as possible.
