set up 2d array python code example
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: two dimensional array python
# Creates a list containing 5 lists, each of 8 items, all set to 0
w, h = 8, 5;
Matrix = [[0 for y in range(h)] for x in range(w)]
Matrix[0][0] = 1
Matrix[0][6] = 3 # error! range...
Matrix[6][0] = 3 # valid
