[New-bugs-announce] [issue26389] Expand traceback module API to accept just an exception as an argument

[Brett Cannon]

New submission from Brett Cannon:

When reading https://docs.python.org/3/library/traceback.html#traceback.print_exception I noticed that everything takes a traceback or a set of exception type, instance, and traceback. But since Python 3.0 all of that information is contained in a single exception object. So there's no reason to expand the APIs in the traceback module that take an exception to just take an exception instance and infer the exception type and grab the exception from exception instance itself.
