What does the 'args' attribute of an exception instance contain?

The arguments passed to the exception constructor

The line number where the exception occurred

A team is building a library that validates user input. They need to raise an error when a username is already taken. The error should be catchable by code that already handles ValueError, but should also be distinguishable from other ValueErrors. What should they do?

Raise ValueError('username already exists') with a specific message.

Use a boolean return value instead of raising an exception.

Define class UsernameTakenError(ValueError): pass and raise UsernameTakenError('username already exists')

Define class UsernameTakenError(Exception): pass and raise it.

When is the else clause in a try/except block executed?

When an exception is caught and handled

When the finally clause is also present

When no exception occurs in the try block

In a try block with multiple except clauses, how does Python decide which except clause to execute?

It randomly selects one of the matching except clauses

It executes the last except clause that matches the exception type

It executes all except clauses that match the exception type

It executes the first except clause whose exception type matches the raised exception

What is a typical use case for the finally clause?

To return a default value when an error occurs

To re-raise the exception after handling

To close a file or release a resource

Exception Handling GPYC Practice Questions (Page 3)

Part of the Python Fundamentals domain, which makes up ~43% of our current practice bank. GIAC (SANS) does not publish an official question count, but from its 120-minute exam (~50–80 total, ~22–34 in this domain), expect 4–7 from this objective — we provide 25 practice questions to prepare you well beyond it.
