Fastest way to get all the points between two (X,Y) coordinates in python

Question

So I have a shapely LineString:

print np.round(shapely_intersecting_lines.coords).astype(np.int) 
>>> array([[ 1520, -1140         


        

Answer 1

Using generators so that way you will save memory

import numpy as np
import math

d = np.array(
    [
        [1520,-1140],
        [1412,-973]
    ],dtype=float);
rise = d[0,1]-d[1,1];
run = d[0,0]-d[1,0];
slope = rise/run;
print slope

fromPt = d[0];
sign = 1
if (slope<0):
    sign = -1;
points = ([d[0,0]+sign*i,math.floor(d[0,1]+(sign*i*slope))] for i in xrange(1+int(math.ceil(abs(d[0,0]-d[1,0])))))
for pt in points:
    print pt
