We can figure out how to pass multiple values computed in Sage back to Webwork. Our example attempt is given below.

# DESCRIPTION
# Problem to test whether sage can print out multiple results

$p1 = -5;$SageCode1=<<END;

p1 = $p1; p2= -10; K = p1+4; Tp = 3/p1 Kv = K/abs(p1*p2) kTpKv = [K, Tp, Kv]; ## print kTpKv print K ### How can we print K,Tp, Kv out and evaluate them separately in Webwork? ##That is ANS($K->cmp()); ANS($Tp->cmp()); ANS($Kv->cmp());
## Right now $result = AskSage can only get one value. ## One possible solution: If we print out a List = [K,Tp, Kv] from Sage, how ##can be get the three values out from List in WebWork?
