To iterate through (access all the entries of) a two-dimensional arrays you need for loops. (Enter the number of for loops needed).

You would need two loops to iterate through both dimensions

Explanation:

matrix = [[1,2,3,4,5],

              [6,7,8,9,10],

              [11,12,13,14,15]]

for rows in matrix:

    for numbers in rows:

         print(numbers)

The first loop cycles through all the immediate subjects in it, which are the three lists. The second loop calls the for loop variable and iterates through each individual subject because they are lists. So the first loop iterates through the 1st dimension (the lists) and the seconds loop iterates through the 2nd dimension (the numbers in the lists).
