Hopefully this should be a fairly straightforward question, I just don't know enough about Python and Django to answer it.

I've got a raw SQL query in Django that takes six different parameters, the first two of which (centreLat and centreLng) are each repeated:

query = "SELECT units, (SQRT(((lat-%s)*(lat-%s)) + ((lng-%s)*(lng-%s)))) AS distance FROM places WHERE lat<%s AND lat>%s AND lon<%s AND lon>%s ORDER BY distance;"
params = [centreLat,centreLng,swLat,neLat,swLng,neLng]
places = Place.objects.raw(query, params)

How do I structure the params object and the query string so they know which parameters to repeat and where?
