How to use the riffle.utils.SyntaxError function in Riffle

for t in types:

            # If primitive type, continue
            if t in [int, float, bool, str, list, dict]:

            # Output should be [bool]

                if len(t) > 1:
                    raise utils.SyntaxError("Lists can only have one internal type.")

                if t[0] in [int, float, bool, str, list, dict]:
                    typeList.append([t[0].__name__])
                else: 
                    raise utils.SyntaxError("Unknown type ", t[0])

            # Same as above-- homogenous key:value pairs, OR just the dict itself
            elif t is dict:
