Answer is Wrong!
Answer is Right!
The correct answer is: A. to_array. append can accept scalar values or any 2-dimensional sequence.
The other options are correct.
- Two kinds of SparseIndex are implemented: integer and boolean.
- The integer format keeps an arrays of all of the locations where the data are not equal to the fill value.
To_array.append can only accept a 2-dimensional sequence. A scalar value is not a 2-dimensional sequence.
