Example 1: python create n*n matrix

# Creates a list containing 5 lists, each of 8 items, all set to 0
w, h = 8, 5;
Matrix = [[0 for x in range(w)] for y in range(h)]

Example 2: 2d array python

array = [[value] * lenght] * height

//example
array = [[0] * 5] * 10

print(array)

Example 3: python print 2d array as table

for row in A:
    for val in row:
        print '{:4}'.format(val),
    print

Example 4: python print 2d array as table
