To make a habit of replying to myself, I thought I'd point out I wrote
it this way mostly because I have no idea how big "settings" is.

If it's not large and only contains keys that are valid identifiers,
it'd be more readable to write:

message = "Item wrote to MongoDB database "
message += "{MONGODB_DB}/{MONGODB_COLLECTION}".format(**settings)
log.msg(message, level=log.DEBUG, spider=spider)
