I'm wondering if someone could take some time to review this script. I'm parsing through a list of points of any length and calculating the distance. I'm wondering how to make my code better/more efficient (something I'm working on). A sample input file would be like so:
300.754178236262248 103.453277023380423 0,276.62980277988612 90.123295023340319 0,269.345711570634421 103.319531391674346 0,293.447811515317824 116.649513392506364 0,300.754178236262248 103.453277023380423 0
I'm not sure why the zeros are there; these are from the spacenet label csv's.
And this is my code:
import math def calc(x1, y1, x2, y2): dist = math.sqrt((x2-x1)**2 + (y2-y1)**2) return dist li =  res =  with open("/Users/jin/points.txt") as filestream: for line in filestream: temp = line.split(",") #splits by the comma in a single list for i in temp: temp = i.split(" ") #splits by spaces to individual lists of points li.append(temp) #list of lists containing each point # for item in li: # x1 = item # y1 = item # for item in li: # for pt in item: # print pt for index in range(len(li)-1): one = li[index] two = li[index+1] x1 = float(one) y1 = float(one) x2 = float(two) y2 = float(two) res.append(calc(x1, y1, x2, y2)) print res
