pandas.Series.bool#

Series.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

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.
