Exception object details

What this problem practises

Exceptions are control flow. except clauses are matched top to bottom, finally runs even after a return, and catching too broadly hides the real bug behind a generic message.

This is an output-prediction problem: read the snippet carefully and write down exactly what it prints before anything runs. These questions are interview staples because they test whether you know the language rules, or merely recognise their syntax.

Difficulty: hard — the naive reading is wrong, and the answer depends on tracking state precisely through the snippet.
