tuple error

I'm running python 3.6 through spyder and trying to run comtypes to control SAP2000. I keey getting this error

File "E:\pyth2\lib\site-packages\comtypes\__init__.py", line 659, in call_with_inout
if len(outargs) == 1: # rescode is not iterable

AttributeError: 'tuple' object has no attribute '__ctypes_from_outparam__'

I have tried modifying the code with the 'try/except' block that comes up as the easy solution to this problem, but no change yet. Any suggestions? Thank
