I am using ARCGIS 10. I have 1200 addresses or points in file A. I have 1600 addresses or points in file B. I need to find the road distance between each point in file A and each point in file B. I know that there should be a way to do this in network analyst. I also know that it my need some python coding for the loops. How can I do this and if it takes python coding does anyone have any code. I have never coded in python
