pySCG typo or error in CWE-703/CWE-392/compliant03.py

The CWE-703/CWE-392/compliant03.py

code has an error on line 22

        ret = list()
        invalid_arg = 0
        try:
            for res in result_gen:
                ret.append(res)
                invalid_arg += 1
            return ret

Not sure if its a typo, got flagged while using pyre.
Need to have a close look to understand the original intention of this code in order to fix it.
