Working with the world collection of countries

These examples introduce NoSQL using MonogDB and PyMongo under Python3.4. We will be using the find() command and basic comparison functions on the collection world:

Use find() to return the 21st document in world
For help on this click here

Show the 21st document in world

pp.pprint(
    db.world.find()
)

pp.pprint(db.world.find()[20])

Use sort() to find the last document in world

Show the last document of world

pp.pprint(list(db.world.find().sort("$natural", -1).limit(1)))
