Python For GCSE
Lists Of Lists

Python allows us to use lists as items in lists. In other languages, this can be done with a two dimensional array.

In order to access items in a list of lists, we use two sets of square brackets.

grid  = [[0, 1, 2], [3, 4, 5], [6, 7, 8]]
for y in range(3):
    for x in range(3):
        print(grid[y][x], end="")
