7,961 PointsAs you've defined it, to_json currently takes no arguments. You need to declare a variable in the parameter list of your function; something like:
def foo(bar):
return bar
The next step is to use the appropriate method from the json library to convert the argument to a JSON string. You will probably want to save that somehow or return the converted value.

18,173 PointsBummer! to_json() takes 0 positional arguments but 1 was given
import json def to_json(): return json.stringify(old, new) return to_json
this worked out better, but did not pass. is there a different method to use?

18,173 Pointsyipee! =D the solution was simpler than first thought.
Craig Dennis
Treehouse TeacherHey I'm wondering....Why the two return statements?
michaelangelo owildeberry
18,173 PointsOne for conversion and one for relay =)
Craig Dennis
Treehouse TeacherYou can only really have one return statement. The first return will exit the function the following line will never be reached.
