pandas.Series.bool¶

Series.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

bool: The value in the Series or DataFrame.

DataFrame.astype: Change the data type of a DataFrame, including to boolean.
numpy.bool_: NumPy boolean data type, used by pandas for boolean values.

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
