Question 1

Basic try/except

Accepted Answer

int('hello') raises ValueError. The except clause catches it and prints 'bad input'. Execution then continues normally after the try/except block — 'done' is printed. The key point: after the except block runs, the program does not crash and execution resumes at the line after the try/except.

Question 2

Catching the right exception type

Accepted Answer

10 / 0 raises ZeroDivisionError. Python checks except clauses top to bottom and uses the first one that matches. ValueError does not match ZeroDivisionError, so it is skipped. ZeroDivisionError matches and 'divide by zero' is printed. Always catch the most specific exception you expect. Catching a broad Exception or BaseException can hide real bugs.

Question 3

finally always runs

Accepted Answer

finally always executes — whether an exception occurred, was caught, or was not raised at all. It even runs if there is a return statement in the try or except block. finally is used for cleanup that must happen regardless of outcome: closing files, releasing locks, disconnecting from a database. The 'with' statement automates this pattern.

Question 4

finally runs even when no exception occurs

Accepted Answer

No exception is raised, so the except block is skipped. The finally block still runs — it executes regardless of whether an exception occurred. After finally completes, execution continues normally with 'after'. This guarantees cleanup code always runs, which is why finally is the right place for things like closing database connections.
