pandas.DataFrame.bool#

DataFrame.bool()[source]#

Return the bool of a single element Series or DataFrame.

Deprecated since version 2.1.0:bool is deprecated and will be removed in future version of pandas.ForSeries usepandas.Series.item.

This must be a boolean scalar value, either True or False. It will raise aValueError if the Series or DataFrame does not have exactly 1 element, or thatelement is not boolean (integer values 0 and 1 will also raise an exception).

Returns:

Examples

The method will only work for single element objects with a boolean value:

>>>pd.Series([True]).bool()True>>>pd.Series([False]).bool()False

>>>pd.DataFrame({'col':[True]}).bool()True>>>pd.DataFrame({'col':[False]}).bool()False

This is an alternative method and will only workfor single element objects with a boolean value:

>>>pd.Series([True]).item()True>>>pd.Series([False]).item()False
