Return all documents
pp.pprint(list( db.world.find() )[0]) pp.pprint(list( db.world.aggregate([{"$match":{}}]) )[0])
Returning the first document
pp.pprint(db.world.find_one()) pp.pprint(db.world.find()[0]) pp.pprint(list(db.world.find().limit(1))[0]) pp.pprint(list(db.world.aggregate([{"$limit":1}]))[0])
Returning the nth document
n = 50; pp.pprint(db.world.find()[n-1]) pp.pprint(list(db.world.find().skip(n-1).limit(1))[0]) pp.pprint(list(db.world.aggregate([{"$skip":n-1},{"$limit":1}]))[0])
Returning the last document
pp.pprint(db.world.find()[db.world.count()-1]) pp.pprint(list(db.world.find().skip(db.world.count()-1).limit(1))[0]) pp.pprint(list(db.world.aggregate([{"$skip":db.world.count()-1},{"$limit":1}]))[0])
