Provided Methods

In case the inner dtype DataType::Utf8, the individual items will be joined into a single string separated by separator.

Get the value by index in the sublists. So index 0 would return the first item of every sublist and index -1 would return the last item of every sublist if an index is out of bounds, it will return a None.
