      Incidentally, for anyone who hasn’t typed ‘import antigravity’ into an interactive Python terminal…you should - as Dr Seuss says, “These things are fun, and fun is good.”

        I love how it contains exactly one function: from antigravity import geohash

        Hell, this is the entire antigravity library:

        import webbrowser
        import hashlib
        
        webbrowser.open("https://xkcd.com/353/")
        
        def geohash(latitude, longitude, datedow):
            '''Compute geohash() using the Munroe algorithm.
        
            >>> geohash(37.421542, -122.085589, b'2005-05-26-10458.68')
            37.857713 -122.544543
        
            '''
            # https://xkcd.com/426/
            h = hashlib.md5(datedow, usedforsecurity=False).hexdigest()
            p, q = [('%f' % float.fromhex('0.' + x)) for x in (h[:16], h[16:32])]
            print('%d%s %d%s' % (latitude, p[1:], longitude, q[1:]))
        

        He literally gets a 32-bit hash, uses the first half of it as the latitude decimal, and the second half of it as the longitude decimal,
