Terry J. Reedy <tjre...@udel.edu> added the comment:
Marking what expression evaluated to None would be extremely helpful. So would
marking the 0 denominator when there is more than one candidate: "e = a/b +
c/d". It should be easy to revise IDLE Shell's print_exception to tag the
span. In some cases, the code that goes from a traceback line to a line in a
file and marks it could do the same.
What would you do when the expression is not the last line?
try:
x/y
...
except Exception as e:
...
raise e
The except and raise might even be in a separate module.
I look forward to the PEP and discussion.
