Function Signature:​

def get_exception_info() -> tuple[str, int] | tuple[None, None]:

Parameters​

  • None

Returns​

  • tuple[str, int]: A tuple containing the filename and line number of the exception if an exception was raised.
  • tuple[None, None]: If no exception information is available, it returns a tuple of None values.

Example Usage​

    # Example code that raises an exception
    1 / 0

Notes​

  • This function uses sys.exc_info() to retrieve information about the most recent exception.
  • If an exception traceback is available, it extracts the filename and line number from the traceback object.
  • If no exception is available (or no traceback is present), it returns None for both values.
