Arguably one of the best use cases for the walrus operator is when debugging complex expressions. Say that you want to find the distance between two locations along the earth’s surface. One way to do this is to use the haversine formula:...
Users of our US Zip Codes, US Cities and World Cities databases often need to calculate the distance between two geographic coordinates (in lat/lng). Since the earth is a sphere, you can't use the distance formula that works for two points in a plane. Instead, you should use the Havers...
