What does the else block in exception handling do?

Question

BlackTom AI · Accepted Answer

To tackle the question, first recall how try/except/else/finally blocks behave in exception handling. The else block is designed to run only when the code in the try block completes without raising an exception. It is skipped if any exception is raised in the try block, in which case control moves to the except block (if present) or further error handling.

Option 1: 'Runs if an exception was raised' is incorrect. If an exception occurs, control transfers to the except block (or propagates), and the else block does not execute.

Option 2: 'Runs if no exception was raised' is correct. The else block executes when the try block completes successfully without errors, providing a place for code that should run only after a successful try.

Option 3: 'Runs only if finally fails' is incorrect. The finally block runs regardless of whether an exception occurred, and there is no conditional connection between finally and else in terms of failure of finally.

Option 4: 'Handles syntax errors' is incorrect. Syntax errors occur during parsing before runtime and are not handled by a try/except block in normal execution flow; they prevent the program from running at all.

Option 5: 'Logs all exceptions' is incorrect. Logging is not automatic for all exceptions unless explicit logging code is placed in an except block; the else block does not perform logging of exceptions.

Option 6: 'Runs after finally' is incorrect. The else block runs before the finally block when no exception occurs, and finally runs after except/else blocks complete, not after finally.
