Examples
Example with a list that contains a None element.
>>> s = ps.Series([['lion', 'elephant', 'zebra'], ... ['cat', None, 'dog']]) >>> s 0 [lion, elephant, zebra] 1 [cat, None, dog] dtype: object
Join all lists using a ‘-‘. The list containing None will produce None.
>>> s.str.join('-') 0 lion-elephant-zebra 1 None dtype: object
