Get all numbers between two points on a graph

Question

class Grid:
def __init__(self, x, y):
self.x = x
self.y = y

cols = 22
rows = 16
grid = [0 for i in range(cols)]

for node in range(cols):
grid[node] = [0 for node in range(rows)]

for x in range(cols):
for y in range(rows):
grid[x][y] = Grid(x, y)

and I have two random coordinates, for example, (3,1) and (5,1), how would I get all the numbers on the graph between those two points? PS: the points could also be like this : (1,3) and (1, 5)

Answer 1

I would recommend looking into the Bressingham line algorithm for this purpose.
