Interview Pro Tip
Red Flag: Empty `except: pass` or catching `Exception` and not re-raising. Pro-Move: 'I catch specific exceptions, log with stack traces, use finally for connection cleanup, and have a top-level handler for unhandled exceptions in long-running services.'
Use `try` / `except` / `else` / `finally`. **Example**: `try: x = 1/0\nexcept ZeroDivisionError as e: logging.error(e)\nelse: print("ok")\nfinally: resource.close()` **Why it matters**: Proper handling avoids cascading failures and enables cleanup. **Architectural implication**: Bare `except:` swallows all exceptions including `KeyboardInterrupt`—dangerous in production. Use specific exceptions and re-raise when needed....
