extends the capability of truthiness evaluation beyond the standard Python truthiness rules to handle pandas DataFrames/Series and NumPy Arrays

pip install istruthy

Tested against Windows 10 / Python 3.10 / Anaconda

    Args:
        x: A value of any type.

    Returns:
        bool: True if the value is truthy, False otherwise. If an exception occurs while evaluating `x`,
              False is returned unless `x` is an empty sequence (e.g., an empty list, tuple, or string),
              in which case True is returned.
