pandas.DataFrame.bool¶
- DataFrame.bool()[source]¶
Return the bool of a single element Series or DataFrame.
This must be a boolean scalar value, either True or False. It will raise a ValueError if the Series or DataFrame does not have exactly 1 element, or that element is not boolean (integer values 0 and 1 will also raise an exception).
- Returns:
