Can you state more clearly the problem, please? I'm seeing output that
can't have come from the code posted (for instance, immediately after
the "at finally", I'm expecting to see the "chunks =" line), and I'm
not seeing any exception information, so I can't even hazard a guess
as to what's throwing the exception.
Presumably these are two methods in the same class, since you're
calling it as "self.chunkLine", but beyond that, it's hard to know.
Take off the try/except and let your exception go to console, that's
usually the easiest thing to deal with.

Sorry, but it *DID* come from the code posted. Which is why I was so
confused. I finally tracked it down to "self was not defined" by
altering the except section to read:
except BaseException as ex:
print ("caught exception")
print (ex)
finally:
print ("at finally")
The documentation section covering the except statement could stand to
be a *LOT* clearer. I read the sections on the except statement and
exception handlers several times and couldn't figure out was the "as"
argument of the except statement was for. "Target" doesn't communicate
much to me. The one I finally used as indicated above was modified from
some code that I found through Google. I still don't really know what
"as" means, except that if you use it, and you print out the "target",
you'll get some kind of informative message. (The one that I got said
"self was not defined" .. that's a paraphrase. I can't remember the
precise wording.) And that interpretation is based on what the result
was, not on anything said in the documentation.
IIRC, the Python2 documentation used code examples to indicate what was
the right way to write an exception handler. I realize that Python3 is
much different, but that approach was a very good one.
