Take

Take[list,n]
gives the first n elements of list.

Take[list,-n]
gives the last n elements of list.

Take[list,{m,n}]
gives elements m through n of list.

Take[list,seq1,seq2,]
gives a nested list in which elements specified by are taken at level i in list.

DetailsDetails

  • Take uses the standard sequence specification:
  • Allall elements
    Noneno elements
    nelements 1 through n
    -nlast n elements
    {n}element n only
    {m,n}elements m through n inclusive
    {m,n,s}elements m through n in steps of s
  • Take can be used on an object with any head, not necessarily List.
  • Take[list,seq1,seq2] effectively extracts a submatrix from list.
  • Applying Take to a SparseArray object normally yields another SparseArray object.
  • Applying Take to an Association object yields an Association containing elements from the specified positions.
