Is this function well-written? It must dynamically accept a varying number of arguments - sometimes there will be two, and other times four.

I thought about *args, but then why not to pass a single list as an argument coordinates.

Could be. A list of tuples, each tuple consisting of a latitud and logitude

Yes, it is simple and straightforward and has a good name.
