# How to | Get Elements of Lists

Lists are very important structures in the Wolfram Language. Lists allow you to treat any kind of collection of objects as a single entity. Sometimes you need to pick out or extract individual elements or groups of elements from a list.

Set up a list of the first 10 squares (stored as v):

 In[1]:=
 Out[1]=

Use Part to pick the third element of the list:

 In[2]:=
 Out[2]=

Or use [[...]] (the short form notation for Part):

 In[3]:=
 Out[3]=

Combine ;; (the short form for Span) with Part to pick out the elements from 1 to 5:

 In[4]:=
 Out[4]=

Pick out elements 5 through 8 of the list:

 In[5]:=
 Out[5]=

Pick the last 7 elements (negative indices count from the end):

 In[6]:=
 Out[6]=

A matrix in the Wolfram Language is a list of lists of the same length. You can pick out elements from a matrix just like you would from a list.

Set up a 5×5 matrix of integers:

 In[1]:=
 Out[1]=

Use MatrixForm to see it laid out as a matrix:

 In[2]:=
 Out[2]//MatrixForm=

The first part of the matrix is the first row:

 In[3]:=
 Out[3]=
