❓ FAQ
QWhat is the execution order of `try`/`except`/`else`/`finally`?
AFirst the `try` block runs. If it raises no exception, the `else` (if present) runs next, and finally `finally` runs regardless of exceptions. If an exception is raised, the `else` is skipped, a matching `except` runs, and then `finally` runs last.
QWhat happens if no exception type follows `except`?
AIt catches every exception, including ones you usually should not swallow like `KeyboardInterrupt` and `SystemExit`. A bare `except` is generally discouraged; prefer `except Exception:` or a more specific type.
QCan variables assigned inside the `try` block be used in the `except` block?
AYes. Python has no block-level scoping, so as long as `try` reaches the assignment line, the variable is accessible in `except`, `else`, `finally`, and after the `try` statement.
