pandas.Series.notnull#

Series.notnull()[source]#

Series.notnull is an alias for Series.notna.

Detect existing (non-missing) values.

Return a boolean same-sized object indicating if the values are not NA. Non-missing values get mapped to True. Characters such as empty strings '' or numpy.inf are not considered NA values. NA values, such as None or numpy.NaN, get mapped to False values.

Returns:

Series: Mask of bool values for each element in Series that indicates whether an element is not an NA value.
