[Tutor] Help with two .shp file and python coding

[Tariq Khasiri]

Thanks for clearing up the matter of what I was trying to ask.

measuring the distance from each interstate intersection to ITS nearest
county border - is my end goal.

I apologize for being vague.

Before doing so I wanted to make sure I'm on the right path since I have no
prior experience working with shp files with python code. So, before
jumping in I wanted to be assured that this is the right way to go forward
given the shp files.
