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 seqi are taken at level i in list.

Details

• Take uses the standard sequence specification:
•  All all elements None no elements n elements 1 through n UpTo[n] elements 1 up to at most n, as available -n last 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.

Basic Examples(6)

Take the first 4 elements from a list:

 In[1]:=
 Out[1]=

Take the last 3 elements:

 In[1]:=
 Out[1]=

Take elements 2 through 4:

 In[1]:=
 Out[1]=

Take the second element from an Association:

 In[1]:=
 Out[1]=

Take all but the first element from an Association:

 In[1]:=
 Out[1]=

Take every other element from 2 to 6 from an Association:

 In[1]:=
 Out[1]=
