1. What is the purpose of exception chaining using the `from` keyword?

Link multiple exception handlers together

Preserve the original exception context while raising a new one

True

False

Sys

Traceback

Exceptions

Error

6. What is the function of `sys.exc_info()` in exception handling?

Clears the current exception

Both A and B are acceptable in most cases

8. True or False: You can have multiple `except` blocks for the same `try` block.

True

False

9. What does the `enter` method in a context manager return?

Nothing; it returns None

A resource object to be bound to the `as` variable

A boolean indicating success

An exception instance

10. Which of these is the correct syntax for raising an exception with a custom message?

Raise ValueError 'Invalid value'

Raise 'Invalid value' ValueError

ValueError('Invalid value')

11. Which built-in exception class is the base for all non-system-exiting exceptions in Python?

BaseException

Exception

RuntimeError

StandardError

12. True or False: The `else` block in a try-except statement executes if no exception occurs.

True

False

13. Which exception type should you raise when a function receives an argument of inappropriate type?

ValueError

TypeError

AttributeError

KeyError

14. When you catch an exception using `except Exception as e`, what does the variable `e` represent?

The exception class name only

The exception instance with traceback info

A string error message

The line number of the error

15. What is the correct order of exception handling when multiple `except` blocks are used?

General exceptions first, then specific ones

Specific exceptions first, then general ones

Order does not matter

Alphabetical order by exception name

16. Which method must be implemented in a context manager class to define cleanup behavior?

__enter__

__exit__

__init__

__cleanup__

17. What does the `with` statement primarily accomplish in exception handling?

Catches multiple exception types

Ensures resources are properly managed via context managers

Defines exception handlers

Creates nested try-except blocks

18. In Python, which keyword allows you to re-raise the current exception?

Raise exception

Raise

Retry

Rethrow

19. What is the primary purpose of the `finally` block in exception handling?

Catch specific exceptions

Execute cleanup code regardless of exceptions

Re-raise caught exceptions
