Two Dimensional Array
➢ A 2 D array is a n array of arrays that ca n be represented in matrix form
like rows an d colum ns. In this array, the position of data elements is
defined with two indices instead of a single index.
➢ Array_name = [rows][columns]
➢ Array_name = [ [m1, m 2 , m 3 , … . mn], [n1, n 2 , n 3 , … . . nn] ]
*Where m i s the row an d n i s the co lumn of the table
Accessing Two Dimensional Array
➢ We ca n access elements of a two-dimensional array usi ng two indic es .
The first index refers to the indexing of the list an d th e second index
refers to the position of th e elements . If we define only one index with
a n array n am e, it retur ns all the elements of 2-dimension al stored in the
array.
Create Simple Array
➢ mahasiswa = [ [82, 75, 67, 95, 70], [70, 97, 85, 79, 75], [86, 71, 80,
68,
• 93], [80, 73, 81, 94, 89], [57, 79, 86, 79, 80] ]
➢ print(mahasiswa[3]) ? ? ?
➢ print(mahasiswa[1][3]) ? ? ?
