Vectorizing Haversine distance calculation in Python

Question

I am trying to calculate a distance matrix for a long list of locations identified by Latitude & Longitude using the Haversine formula that takes two tuples of coordinat

Answer 1

start by getting all combinations using itertools.product

 results= [(p1,p2,haversine(p1,p2))for p1,p2 in itertools.product(points,repeat=2)]

that said Im not sure how fast it will be this looks like it might be a duplicate of Python: speeding up geographic comparison
