[Chicago] Unexpected indent: secondary damage in syntax error?

Sat Oct 20 15:01:53 EDT 2018

Dear Christos,
I went over your code and in addition to the try: without except you had
multiple issues with indentation which I have attempted to correct (but I
could have also changed the logic in your program).  Also, I refactored
your two trys into one try that goes over the whole loop. I assume this was
also written with python 2.7 and you had print statements that were using
python 3.x print syntax.
Sincerely,
Joshua herman
